Really good, modestly-scoped gimmick hack. You might die a couple times when exploring, and a certain boss is quite challenging for what it is, but otherwise this isn't too hard (imo).

Bonus points for the Metroid 2 nod in the level design.

As far a Metroid 1 hacks go, you could say the quality of this is... *puts on sunglasses* over the moon.

*audible groans*

The world design of this is nice, compact, dense, and rather well-considered. After the starting hump it becomes rather open-ended, and rewards memory and observant-ness. I highly recommend mapping this by hand, making note of obstacles as you go.

The early game when you're low on missiles can be a bit too much. Also I give you permission to quit once you reach Tourian if it gives you trouble (the rinkas are also a bit much). Other than that, this is a pretty swell experience.

The first Metroid hack ever, and it's actually pretty solid. It avoids a lot of flaws endemic to many, many later Nestroid hacks, such as being ambushed when popping out of doors, and it even manages to avoid a problem that plagued the original game: getting sniped by pipe bugs in the middle of a door transition. In other words, the designer of this hack was quite aware of the limitations of the original game, as well as the tools they had back in 1999.

If I had to level a complaint against this, it would be that the world design is a bit too straightforward (Kraid's Lair especially), and that there aren't any hidden secrets -- though folks who find vanilla Nestroid too obtuse and hard to navigate might appreciate those facts.

Still one of the best Nestroid hacks, even 21 years later.

Decided to replay this on whim. Only died once or twice.

Years later and this is still brilliant and beautiful, and still in my top 3 SM hacks.

Don't let the frontloaded difficulty get you down. Be cautious, but take risks, and just allow yourself to be immersed in the world.

Eris 2012 has some very smart changes over the original that I didn't appreciate at first. I recommend it over the original, especially for first-time players.

I can usually beat vanilla Nestroid in one sitting, so this patch alone isn't too useful to me personally, but it has been a major quality of life improvement in all the hacks that use it. If you're making a Metroid 1 hack, use this.

Wavy-ice is a great bonus. I have a few issues with the map functionality, but it's fine.

Source is included, which is always a plus.

One of the top 2 hacks where Samus goes to the fridge to get a glass of milk. Highly recommended for all of you fans of hacks where Samus goes to the fridge to get a glass of milk. If you are not sure if you're a fan of hacks where Samus goes to the fridge to get a glass of milk, then you should play this hack where Samus goes to the fridge to get a glass of milk. If you are not a fan of hacks where Samus goes to the fridge to get a glass of milk, then maybe you should go to the fridge to get a glass of milk yourself, buddy.

Not recommended if you are lactose intolerant.

Really pretty looking, and some nice custom music. Some standout ASM work as well.

The whirlwinds feel a bit too finicky to navigate and I take some issue with the lack of refills from (most) enemies. The result is that the game always feels like it's providing almost a little too much friction against the player.

Other than those complaints, this is pretty solid all around.

Cool challenge hack. It has some teeth, though it's a bit easier than what the concept might imply. I beat it deathless on my first attempt, though I was generally quite cautious and meticulous in my approach.

This is a pretty nice, modestly-scoped hack. Color me impressed.

The custom music is appreciated, even if it sounds like plunky midis.

The extra aerial horizontal speed feels nice, though is a bit hard to get used to at first (especially with the gravity being unchanged).

I played this back in the day, making a map on paper as I went along. I still had that map somehow, so I played it again using that map. Thankfully, that map was pretty accurate, so I was able to beat this fairly quickly.

The custom graphics are nice, and the attempt at modified music is appreciated -- the songs in Brinstar (and Brinstar only) seem to use slightly different instrumentation (but not always for some reason).

Anyhow, I don't have too much to say about this hack. I liked it. It's a bit tougher than the original game, but if you're good at Nestroid I recommend it.

Odd issue: The player sprite was glitched out when I first started, but dying loaded the graphics properly.

The progression, especially towards the beginning, is rather ping-pong-y, but other than that this is one of the best hacks of the pre-2005 Metroid hacking era.

Pretty nice graphics hack. Certain things look a bit too glossy for my tastes. I would have preferred something that changed the tiling, and not just the individual tiles, but what we got is okay.

The level design changes (mostly the item rooms) are tasteful.

There are a couple of extra missile tanks in this, but it appears that you lose them if you die.

While this hack isn't bad by any stretch, it definitely does feel like a half-finished hack that was handed off to somebody else. There is a decidedly noticeable drop in ambition and ideas as the game progresses. Brinstar and Norfair are quite good and well realized, Kraid's Lair is mostly good by feels half-baked aesthetically, and then Ridley's Lair and Tourian feel like minor rearrangements that only use screens from the vanilla game.

Still, nothing in this hack is really bad, and as someone who likes Nestroid I found this to be quite swell.

Be aware that a couple items are gated behind unmorph-jumping and unmorph-bomb-jumping-into-a-respawning-tile.

This is basically Y-Faster, except bigger, longer, and a fair bit more difficult. (How much one likes those qualities depends on the person, but that's just what the hack is.)

Eh. I like the background graphics from 'Roidz, but the most all of the MBDtroid sprites feel like a downgrade compared to sprites from 'Roidz. Also, I take issue with the removal of the tasteful level design changes 'Roidz made.

This is like if Project Base was just a set of alternate palettes, but didn't make any meaningful changes to the gameplay or world. I just don't see the point, really.

Still, the wave-ice combo is nice at least.

Silly little crossover hack. Decently crafted, some jank aside (like the nasty GFX errors one the player sprites).

A map was provided, so I played with it in the background. The map design is a little spread out, and the areas overlap sometimes, but the map layouts are fundamentally pretty simple compared to the original, with only a couple exceptions (like a one-way door here and there). Maybe I shouldn't have used the map (idk).

I lost like 15 minutes of time because the Ice Beam did not spawn in its backup position behind the statues, meaning I had to trek all the way to the Norfair Ice Beam to get it. That kinda spoils my mood to recommend it to be honest, though it's probably fixable.

I enjoyed this more than I expected. It has a couple issues, but it's not bad.

There's a softlock about halfway through Brinstar if you don't have bombs. Also, if you get the Wave Beam and want to return to Brinstar-proper, your options are either (a) deathwarp, (b) wallcrawl, or (c) trek deep into Norfair to fetch the other Ice Beam.

Despite those issues, I found this quite playable and easily mappable by hand. Contrary to its name and what the description may suggest, this is not really much a challenge hack. It's generous with e-tanks, the map design isn't too convoluted, and you can get Varia rather early.

If the ROM was expanded so some of the dead ends could be pruned (by adding more room-types) and wave-ice was added, this would be a decently solid recommendation.

The ending text gave me a chuckle.
Metroid Ridley X Hack by Ridley X [M1 Exploration], rated by RT-55J on Jun 03, 2020 (Star Star Star Star Star )

Not bad, rather polished, but not great.

I like the Metroid 2 graphics, but this hack only takes only a fraction of that game's tilesets, so all the areas end up looking too similar.

Brinstar feels decently well-realized, but the other areas not so much. Overall the map design is a bit too sprawling, sparse, and repetitive. The worst culprits are the two-column vertical shafts in Norfair (overly tall and dreadfully boring). If this was an old hack, I'd be a bit more forgiving, but this is a newer hack that uses an expanded ROM.

This hack has a lot of elevators, and each area ends up being a set of non-contiguous sub-areas. Unfortunately, the sub-areas of each area don't really do too much design wise to differentiate themselves. It gives the hack a slightly bizarre sense of space.

Brinstar has a good number of secret passages, but the other areas are pretty straightforward.

Both Wave and Ice are far enough out of the way that this hack could have used the wave-ice patch.

After defeating Kraid I looked at the editor for where to progress, because I ran out of options on the map I was making. It turns out the path forward was just a hidden path in an elevator room. After Ridley I was done with the hack and just made a beeline towards Tourian.

I do appreciate the fact that the hack is nice and easy, relatively speaking. The game is fairly generous with e-tanks early on, varia is accessible pretty early, enemy placement is reasonable, and Tourian isn't too hard. Good job on nailing the difficulty.

The most notable thing about this is that it's for the PAL version. It's worth playing just to hear the PAL arrangement of the soundtrack (did you know: the music for European Nestroid was subtly and tastefully adjusted).

Decent hack for what it is. Most of the original background graphics are amateurish, but fitting. I like it.

Not very many level design changes outside of Brinstar.

Vanilla map and item layout. Brinstar is tough at first, but after you get some decent equipment it's fine.

While the main portion of each area's tileset was changed, it looks like most of the shared tiles were not. Slightly disappointing, given the quality of the tile and sprite work.

I wish this were finished.

Map and item layout is identical to the original. However, all the individual screens are changed in every area however (except for Tourian, which was unchanged). The requirements for only a couple items were changed, from what I saw.

If you know the original game you can beat this in an hour.

Not bad, but not really interesting either.

Decent hack for it's time. It has a few clever ideas, not that many glitches, and avoids the sheer bloat that a lot of its contemporaries ran into. Early-game pacing is also relatively brisk compared to most.

The general skeleton of the map is vanilla-ish, but item placement has been shuffled around compared to the original (unlike most hacks of this era) -- this comes with the side effect of some expansions respawning, but that's excusable given its age.

The design of each of the screens is a bit uneven --- they tend to either be slightly too rough or slightly too featureless, if that makes any sense.

I ran into a scrolling glitch in Ridley's lair, but thankfully it was relatively easy to fix (no OoB shenanigans needed).

Overall, this isn't really bad at all, and is one of the few hacks from this era that I'm willing to recommend.
Metroid: Wart's Invasion by AlexAR [M1 Unknown], rated by RT-55J on May 17, 2020 (Star Star Star Star Star )
100% in 1:52
This hack is worth three orbs, but the primer on Metroid 1's bomb jumping is worth 5 orbs if you can decipher the ascii diagrams. Unfortunately, I'm reviewing the hack, not the readme.

Presentation wise, I give this a nice, solid B+. The enemy sprites are generally cute, though its clear that the author struggled to find a good Mario equivalents to sidehoppers and swoopers. Unfortunately the screen layouts are just aesthetically very messy, and don't end up feeling very Mario-like. Also, it's kind of disappointing that the music wasn't changed at all (though I can't really blame them).

The difficulty is kind all over the place. Kraid's Lair comes before Norfair in this, which is weird because the enemies in Kraid deal twice as much damage. You get the Wave Beam nice and early (the Correct design decision if you don't have the combined Ice-Wave patch to work with), but you get the Varia Suit too late to really make a difference (honestly its place probably should have been switched the the Screw Attack). Fortunately, both the minibosses in this are pushovers thanks to how their arenas are laid out.

The moment-to-moment level design is what drags this game down. The amount of navigation this game expects you to do with bombs gets very tedious by the end. It feels like at least one-third of the screens have you doing some sort of bomb-jumping shenanigans, and it gets kind of tedious. Fortunately, the linearity of the hack means that you rarely have to do any backtracking.

The hardest part of Tourian was not the final boss or the metroid stand-ins, but rather doing bomb jumping while being assaulted by rinkas.

Not too bad of a hack, but not too good of one either.

100% in 0:50
Hack over-achieves at its own goals, resulting in something that feels _too_ streamlined. This is most egregious with Norfair, where the entire half of the area behind the hi jump boots was simply excised. I thought the in-game map was lying to me when I saw that, but nope, that area really does not exist anymore.

Also, the attempts at breaking up the repetition of the original game's areas are commendable, these efforts are undercut by things like having 3 identical screens in a row with missile upgrades in Brinstar, or another 4 such screens in a row, also in Brinstar, or yet another 5 such screens in a row, also in Brinstar.

The boss graphics being on the in-game map are a cute touch, but in every area other than Brinstar the graphics are incorrect.

I recommend neither for nor against playing this hack.

I'm becoming a crotchety old man losing his patience for vanilla-style sprawl-fests. You did good work, bud, but this ain't my taste anymore.

The overall map strikes me as very disjointed. Still, in spite of everything of interest being hidden behind some sort of fake/shootable wall/ceiling, there is a certain logic to how the gameworld and navigational puzzles are arranged. For instance, in many cases when you run into a dead end, the path ahead is hidden a handful of screens behind (or in plain sight). Eventually you'll start to be able to read the author's mind, and things will start running a bit more smoothly.

Even so, progression felt overly slow for my tastes, and the world just wasn't compelling enough to keep my interest. (Another issue is that being in school kills my motivation for longform entertainment, but that's beside the point.) By the time I beat Draygon, I was just wishing the hack was over. Fortunately, will say that everything after getting the Screw Attack was smooth sailing for me, so in a sense my wish did come true.

In other words, I give this 2 points for fun, and 1 point because Ridley was kind enough to get himself trapped in a corner just for me.

SM Redesign: Axeil Edition by Drewseph [SM Exploration], rated by RT-55J on May 30, 2015 (Star Star Star Star Star )
74% in 11:46
The level of professionalism and polish Drewseph put into this cannot be mistaken. In terms of look, feel, scope, and aesthetic realized-ness, this blows most other hacks straight out of the water. Props to him for that.

Generally speaking, I would say that this hack accomplished its goal of providing a more accessible version of Redesign, at least up until Tourian. Save for a small handful of in rooms that area, I was able to beat this hack without savestates. Granted, I had beaten the original Redesign twice, but that was over 5 years ago (at the very least). It can still be rather challenging at points, but the most egregious nonsense of the original Redesign has been excised or ironed over (well, except for the 25-missile doors).

Unfortunately, some changes have been made for the worse. Phantoon's AI was changed, making an obnoxious boss even more obnoxious. The Screw Attack is now guarded by an entirely opaque sub-Zelda puzzle. And for whatever reason you can't jump off of crumble blocks. Other reviewers have enumerated more of these negative changes, so I'll forbear.

But I will still talk about Tourian. You see, Tourian has been completely redone from the original Redesign. It's now an absolutely brilliant piece of level design that will leave you frothing at the mouth by the time it is finished with you. It's meticulously well-realized and crafted, but utterly and entirely inaccessible to play, even for the most skilled players. All pretensions of "easier-ness" that this hack had come here to die, again and again and again and again. I don't care how hardcore you think you are, you _will_ hit a roadblock here that will send you into a fit of apoplectic rage. Ultimately, I was able to power through the worst of it (with savestates), but even after the difficulty finally started winding down there those moments left a very sour taste in my mouth.

I wish Drewseph the best of luck in his future hacking endeavors. The guy has a lot more talent than most. If he makes a new world for us to explore, I would hope that it is more restrained in scope.

It's MDbtroid, except a few items are shuffled around like this is a plando or something. Room design seems unchanged aside from a 3 or so screens at the beginning, and the addition of a few missile doors en route to the bombs.

Rather janky and obtuse at times, especially early on... but I kinda liked it. Mind you, it has it's fair share of nonsense, but the graphics are nice and it has a number of clever ideas using wraparound and door blocks. As it stands however, I had to play with the editor open most of the time because I couldn't ever quite trust it as much as I wanted to -- there are a couple places early on I think you can get softlocked, and there are a few too many areas requiring advanced techniques.

The worst bit is at the starting screen, where you have to just barely walk off a platform to do a mid-air jump to get the morph ball. I thought you had to get the high jump first, but as far as I could tell that requires missiles, and the earliest missile pack requires the morph ball.

The second worst bit, that I just wish I could like, a morph ball maze in Norfair that you had to navigate by bouncing. It's a great concept, but suffers because of the difficulty of fitting into 16 pixel tall gaps (if the gaps were 24 pixels tall, then it would be just fine).

The funniest bit is that the item fanfare in Ridley's lair (and only in Ridley's Lair) is glitched out. I thought the game had crashed for a second there.

I actually rather liked Tourian (aside from the escape) -- there's a couple of rather clever ideas there.

Also, I'm not sure what Sapphron is talking about with the Varia. I was able to collect it just fine. The only issue is that I had to go through some doors to fix the scrolling for some reason.

The Kraid fight is easy because you can lodge yourself at point blank range and fire missiles at max speed.

Ridley's fight is weird, since his arena wraps around from the bottom to the top of the map. I didn't even know that was possible.

If someone were to come back to this and polish it up a bit I'd say it would be worth 3 or 4 orbs perhaps.

A slapdash collection of background graphics from other NES games. Looks... okay, I guess? Not really thematically coherent, nor especially good or bad.

The only sprites that were modified appear to be items/pickups, the HUD, and doors.

A funny inadvertent level-design change is that you can vertically screenwrap in a couple horizontal rooms in Brinstar because they changed some of the roof tiles to be non-solid.

Only played for 5 minutes before getting bored.

I'd give this hack an extra orb or two if the permastucks, softlocks, and save data issues were fixed. Going towards bombs without high jump results in a softlock, and it's possible to softlock in the bomb room if you fall down before getting bombs. Also, I lost my first missile tank when dying in Norfair (lame).

As it stands, this feels like a middle of the road hack from 2005. The creaking skeleton of the original item locations can still be felt. Unfortunately, too many of the areas have long, winding, linear paths without much of interest.

The Metroid 2 tiles are nice, as are the parts when the areas overlap.

Recommended if you can tolerate a certain lack of design polish.

Not the last hack of its kind.

"Metroid Mother Visibility Rearranged and Compactified" this over-simplifies the game and trivializes the exploration and discovery. Items are strewn along your path, and many rooms were just removed. To make matters worse, this hack flattens most of the existing rooms, reducing the variety and interest of the game even further. Worse yet, enemies are clumped together, often in groups of 6, so lag is even more of an issue here than it was in the original (since it's harder to get them cycling through enemy slots between screens).

Wave Beam is required to beat the bosses, but the bosses aren't required to access Tourian, and beating Mother Brain isn't even required to beat the game. All you actually need is just 10 missiles, really.

Two doors in Tourian and one door in Norfair lead you out of bounds.

This hack strips the "metroidvania" genre down to its barest skeleton. Truly, a subversive piece of art worth all of your thought (but none of your playtime).

This is a very silly graphics hack. The morph ball turns you into Kirby!

The are some minor changes to the layouts of individual screens. The Brinstar item rooms were rearranged, but unfortunately the position of the items themselves weren't, meaning that they are uncollectable. If you want to play this in its current form, use a password that at least gives you bombs, varia, and long beam.

I fiddled around with this for 30 minutes using the JUSTIN BAILEY password and had a decent enough time.

Note that the intro text in the patch here doesn't match the text in the fourth screenshot. Weird.

This is a middling hack that keeps the skeleton of the original game's map. I'm struggle to think of any interesting ideas it has (other than putting ice at long beam). It was okay to play, but I got bored towards the end.

Energy tanks are hard to come by, and I only found two by the end. Looking at the game in Editroid, I have a feeling something regarding their spawning is bugged, because at least two of them didn't spawn for me, even though I passed right by them.

In Norfair there is an energy tank at the old screw attack location that I did manage to get. However, I had to wall-crawl to get to it because the author changed what column the hole in the floor was on in the room before it, rendering it inaccessible by normal means. Anyhow, when I left that energy tank room the scrolling got messed up because the author accidentally used a horizontal-horizontal door tiles. I had to do some really stupid door-crawling and OoB shenanigans to get scrolling back to normal. That was both the highlight and lowlight of the hack to me.

BTW, if you ever play this, there's a missile tank at the very bottom of Kraid that respawns when you die. It's easy to get to, and I wouldn't be surprised if other items also have that property (this was a common occurrence in old Metroid 1 hacks that changed item locations).

Looking forward to "METOOID REMX II" coming soon.

This hack takes the reputation of Metroid 1 being a sprawling, repetitive, unnavigable mess and takes it as a worthy design goal to surpass. Areas are even larger, more repetitive, and less interesting. A common occurrence in this hack is for there to be a bunch of nearly identical horizontal rooms stacked right on top of each other, and they would all lead to the same two vertical shafts on both end. One might have missiles, the other ones would have bupkis, and that would literally be the only difference.

Several years ago I played this while mapping it by hand. In Kraid's Lair, I eventually found the path to Kraid himself. It was a linear stretch of decently long horizontal rooms with almost nothing but pipe bugs, followed by a 12 screen tall vertical shaft you had to climb, where one mistake could send you all the way to the bottom.

Later, I made it into Ridley's Lair, and after mapping out the elevator room I noticed that Ridley's area dipped below the lowest extremity of Kraid's area. As soon as I saw this, I just knew that I would have do something absolutely stupid like take a horizontal corridor spanning the entire length of the map just to get to Ridley. Upon having this thought I opened up the level editor and took a look at the map, and sure enough that is exactly what the hack's author had done.

I dropped the hack right then and there.

Recently I replayed it to completion with a map in hand, and it was... okay. I still wouldn't recommend it due to its flaws, but is at least polished and not super buggy, which is more than I can say for a lot of other early Metroid 1 hacks.

Be warned though, this hack forces you to 1CC it. Death (and I assume using the Up+A code) boots you straight back to the title screen without any password, and the password screen itself is unusable (all the characters have been replaced by 0). Either bring your skills or your save-states.

Played for 3 minutes and then stopped.

The text on the title screen is AAAAAAglitchedAAAAA.

Samus spawns one block inside the floor.

The screen with the door on the right in the first vertical shaft in Brinstar was changed to require a precise damage boost to get up. The ripper you're supposed to damage boost off of doesn't always spawn, thanks to how enemy slots work in this game.

This is something that a 12 year old with MetEdit would make after screwing around for 20 minutes, and not an actual hack. Barely anything was changed, and what was changed is bad.

This hack has a couple really novel ideas for something without any ASM hacks. It has a couple "teleport stations" that abuse how door blocks work (you see one right at the start). Also, it has special doors in Norfair that you have to shoot at the top or bottom to get working. Both are pretty janky, but are quite neat.

That's pretty much all of the good things I have to say about this hack. Everything else is pretty bad.

Progression is very stingy from beginning to end. There are only 5 energy tanks and 5 missile tanks overall. After collecting morph ball (and I guess missiles), you have to get wave beam in Norfair to get the high jump in Norfair to get bombs and long beam in Brinstar. Both Brinstar and Norfair are a pain to traverse for different reasons, and you likely won't find any energy tanks for this first leg of the journey. After this initial hump the game becomes markedly easier, but that's true of most Metroid 1 hacks. Progression-wise, the only saving grace is that Screw Attack is quite early (if you can find it), but that doesn't save the map design from being way to spread out and sparse and dumb. (Also, it looks like the author anticipated wall-crawling, since there is no way to use it to get main items early.)

In Kraid and Norfair, dying respawns you at the bottom of the elevator shaft. This is annoying in Kraid, but infuriating in Norfair since going down the elevator shaft is a one-way trip, and the way back up basically requires traversing the rest of the area.

The tilework gives me major Hoshi wo Miru Hito vibes. Everything is ugly in the most boring way possible (except somehow their suitless Ridien sprites turned out decent (being minor edits)).

I was tempted to give this hack 2 orbs on account of its clever ideas I mentioned above, but that doesn't save it from being garbage. However, this feels like a marked improvement over the author's previous hack, Metroid Adventure, so take that how you will.

Completed with liberal use of a map and savestates, after an initial attempt not doing that.

Vanilla screens and item placement. Kraid and Ridley's area have okay-ish designs. Norfair is tolerable. Tourian is only slightly changed. Brinstar's design is absolutely hateful.

As far as I can tell, the intended route to bombs in Brinstar is to fall down a vertical shaft that spans the entire left side of the map, go across a horizontal corridor that spans the entire bottom of the map, and then climb almost all the way back up a vertical shaft that spans the entire right side of the map.

The rest of Brinstar's map design isn't quite as ridiculous as that, but it's pretty close. The only saving grace is that the starting point is pretty close to Tourian and the Brinstar Ice Beam.

Completed using a map and with judicious use of wall-crawling and death warping. (I might have been able to cut 10 minutes off that time if I had gotten Ice Beam before Varia (or just skipped Varia)).

I recommend reading the readme just to get an idea of the contempt at work here.

Barebones resprite with a couple text changes. Nothing looks very interesting.

To elaborate on Sapphron's review, it says YOU SUCK when you die, and YOU DIED when giving you a password.

Played 6 minutes before getting bored.

Beyond the grotesque color choices, this slightly shuffled the item progression. However, after playing for half an hour and exhausting my choices of where to explore, I opened up the editor and found that this hack is not completable without wall-crawling --- you need ice beam to get bombs, but both ice beam locations are locked behind bombs.

Charmingly garish and amateurish visually, but absolutely infuriating to play. As the title suggests, almost every single screen is an ordeal.

I was having a decent time despite the high difficulty, until I found out that the intended route to the high jump boots has you take nearly 3 energy tanks of forced damage, by having you to bomb a row of blocks at the bottom of the screen (where you take lava damage) to get around an impassable wall.

I looked at the editor and the path to the screw attack has the same thing, except it's 7.5 screens long. The detailed map says that you need nearly 400 energy and varia to make that trip.

Did not finish.

This would be a two-and-a-half star hack if some of the glitches and softlocks were fixed. As it stands, it's hard to recommend.

Ridley's Lair is the most egregious example. There is a tiling error in one of the structures that leads to most of the morphball passages in the area being unusable (somehow, this is not shown in Editroid). Thus, finishing Ridley's lair requires door-climbing. Also, the energy tank room right behind Ridley looks like a glitchy mess. Kraid's lair is fortunately playable.

Early-game progression is a bit too obscure and too slow, especially with how large Brinstar is. Also, Brinstar has two rooms with doors that take you off the left edge of the map for some reason.

Norfair has an interesting design, but has too many dead ends with nothing on them, even though they have item orbs. (Empty item orbs and chozo statues are also a big issues with Brinstar.)

This is like the Cristener Homenag of Metroid 1 hacks. Immediately grotesque and impressively unplayable.

I remember back when Dragon Eye Studios was still a thing that the author of this hack (who I shall not name) regretted making it. It's easy to see why.

The vertical shafts in this are like if somebody though that the Kraid-climb in the original game (the part with all the breakable blocks) wasn't hard enough, and so just stuffed a bunch of enemies in and arranged everything randomly. If you get hit on your way up you'll end up being combo'd to death as you fall down. It's quite impressive, in a way.

Looking at the level editor, it appears that Brinstar is the only area that is accessible. Kraid and Tourian also appear to have been modified, but are inaccessible (and, oddly, appear to be better-designed). 100% "completion" of this would entail getting morph, bombs, ice, long beam, varia, 2 missile tanks, and 0 energy tanks.

I quit after playing for 20 minutes, because I couldn't see myself making any progress.
