nice graphics and music. the world is pretty open and interesting to explore. when i died in sporespawn area once, it teleported me to a new water area. I'm not sure if it's intended or not, but it didn't affect my playthrough at all. after getting space jump and screw attack, the game became a little less challenging to me. i collected all the items on the map that the map station showed to me, but collection rate was only 66%? i got all the major items except xray, and 14 Etanks 110 missiles 25 Supers 25 powerbombs. BTW, when i reloaded at the final area save station, the graphics in the room was broken.

Soy tier "every patch from project base without actually being project base" "all CRE stolen from Hyper" "player graphics stolen from Opposition" hack. 70% of it is CRE hell and the developer ENCOURAGES you to stay in CRE hell by placing just about every major upgrade save beams, bombs, hj, space jump, and screw attack in CRE hell. The other 30% of it is not visually appealing either, attempts to be more than SM yet still fall flat at escaping sameness. There are also lots of blank room segments that appear past scrolls the dev didn't bother to fill in, likely because he didn't expect the camera to scroll that far. One door in Phytor Ruins when entered from the left takes you to a higher door on exit. Overall not a very difficult hack and okay on fun factor, but it definitely needed polish. And the music is kinda catchy, but nothing special.

This was a fun hack. The first area gave me vibes of a space aged Darkholme Hospital with undertones of SZM pirate ship. Flying through those rooms with speed booster tech with catchy custom music in the background was a blast. The hack's openness leads to some interesting item progression depending on your route and good replayability. The bottom areas seemed heavily Hyper and Ancient Chozo inspired, also with good custom music that fit the areas' vibe. There were some bugs and slope errors, but didn't really detract from the experience for me at least. The only thing I didn't like was the end where after 99.9% of the hack being custom, you get dropped into a Vanilla room for a boss fight and it just ends with no escape. Obviously escapes are cliche, and there was no ship, so I dunno, maybe could have teleported from somewhere. But considering this was made in 6 months for a contest, is huge, had great custom graphics/HUD/ASM/music, QOL edits, I thought it was pretty darn good.

Great soundtrack. Unfortunately, I ran into a hard-lock due to a save-station bug. If you save at the lower station near Spore Spawn without picking up the High Jump Boots, then die, it respawns you in a different save station on the far left of the map near a watery area.

That results in a hard-lock because if you do not have high-jump, you cannot get out of the watery room that the save-station is connected to, while your save still points at that station.

Excellent aesthetics, interesting and unique music, cool mechanics, and a well designed world. I had a lot of fun. I liked how open it was and enjoyed the numerous design elements that allow it to stand out. I wish secret hunting was a little more robust, traversal less straight forward, and more emphasis around the unique mechanics in the game. The place to go use the Chozo keys could also be more clear IMO. The relative symmetry of the map had pro's, ease of exploration, and cons, lack of surprise, but was well done and unique enough to be welcome. Thanks to all who helped, this is a great hack.

Quite good, if really repetitive at times.
Progression isn't quite too obvious but there are a lot of things that make up for it, like the excellent custom tracks and GFX use. Really liked this for its flaws, and especially since it was so large for something made in 6 months!

To be a hack of a contest, it's big, it took me more than 3 hours to finish it and the truth is that those hours I played were fun. I liked his music and graphics, especially his music which is outstanding. The new anti-gravity mechanic isn't new to Super Metroid hacks, but turning Samus upside down is new, I don't know how they pulled that off, but it's technically impressive. I recommend this game because it is fun. Play it!

I'd give it a 3.5/5.

I wasn't a huge fan of the symmetry of the main area especially since it was all CRE which made going from one side to the other feel repetitive at times.
The other areas were fine and the music was great. I really liked that anti-gravity mechanic even if it was only used for a couple rooms.

Still a very solid and fun hack and I recommend it.

There's a lot to like with this hack. For me it was a rollercoaster at times.

I hit the save warp bug. I used IBJ to reach an underwater area (I didn't have gravity) and I got stuck. I was pretty mad at myself because I couldn't remember the last time I saved. When I reloaded I was in some water area. Thankfully I had springball so I used springball jumps to get out of that area and back to areas I should have been in. I thought maybe it was an antisoftlock measure because I wasn't sure if I had lost any progress. So for a while I wandered around thinking it was just a weird way of preventing people getting stuck the way I had.

Aside from that save warp, which ultimately wasn't that big of a deal, the only other frustration I had was that the map was hard for me to understand and navigate. I think the big rooms were sometimes a bit empty feeling due to a lack of enemies. However, I understand this hack was created in limited time by two people. They made a huge world and populating it fully probably just takes way more time than they had. That's pretty much it for things I could want changed.

Overall my experience was very positive. I think this is a good hack that I would recommend to people. I think speedruns of this hack could be a lot of fun, due to all the routing choices you could make. The upside down gimmick was interesting. I really struggled to control samus but it was fun to have a new gimmick in a hack other than "ruin vanilla physics".

I loved the custom music. I think that was my favorite thing. Finding the chozo keys was cool. The big locked gate that opens was epic.

Chad tier "movement improved with various patches" "custom gfx from various hacks and resources" "player graphics from Opposition with permission from Mccad" hack. The developer spreads out items throughout the whole hack encouraging dynamic exploration of the entire world. The whole thing looks either fine to very good, and has very clever usage of vanilla tiles with nice-looking recolors and pleasant tiling. There are also lots of blank room segments that appear past scrolls the dev didn't bother to fill in, likely because the dev was pressed on time and had to save on data in the rom. One door in Phytor Ruins when entered from the left takes you to a higher door on exit, but this is fixed in a later version. Overall not a difficult hack and very fun with impressive polish for such a big hack made in 6 months. And the music is very catchy, I've found myself listening to it at Mentlegen's Music, the creator's youtube channel. 5/5 definitely recommend.

Got soft locked with that save station glitch after a space pirate OHKOd me

Graphics and music looked good. Layout seemed pretty random... Really surprised I some how bee lined it to bombs.

Might try again another time, soft lock caused me to bail

Edit: June 10 2022 Tried again & pseudo soft locked at Draygon (I can't grapple climb)... Haven't saved in forever so bailing again

There are a couple of unique features that stood out for me in this hack. One is the custom soundtrack, which is apparent within moments of starting the game. The other is the anti-gravity gimmick. Soundtrack will be a matter of personal taste as to whether it will be enjoyable but either way, the original compositions make for a unique atmosphere. The anti-gravity gimmick is restricted to a few rooms (understandably since it takes twice the effort to design spaces for two orientations) but isn't overly obtrusive and it's goofy and fun to play around with.

Rest of the gameplay is the familiar Super Metroid loop. Find items to open up new areas to reach more items and repeat until the end goal is complete. Resources and access felt restricted at first until Super Missiles are obtained. At which point, most of the rest of the map opens up and Samus' power level massively spikes. Then it becomes a matter of grabbing stuff in whatever order you please, beating up the occasional boss, until eventually the key hunt is complete. Went from 2 E-tanks to 7 in a short period and once I'd tracked down a suit, didn't feel threatened by hazards for the rest of the game.

The near absence of secret passages supports the category of a race hack. This is one of the least confusing hacks to navigate I've ever played (out of around 20 or so) which could be very welcome for the type of player who struggles with puzzles and/or finding hidden passages. It's not very demanding with the advanced techniques either which makes this approachable to someone without a lot of SM hack experience.

My actual playtime is probably about an hour longer than the listed completion time. Still, this is a quick and compact hack with some unique features to distinguish itself from the crowd.

rounded up from 3.5 orbs to 4

as a contest hack, this is a bit rough around the edges. if you can get over some of the jank it's pretty good. did not collect gravity suit just for fun

I really enjoyed this one a lot. Only one playthrough under my belt but I can see this one getting replayed a lot.

World/map design was phenomenal. I really appreciated the concise yet vast layout of the map.

Room layouts were fantastic. They were fun to traverse and enemies were appropriately challenging. While there were certainly a few puzzles, I appreciated that there were not any cryptic rooms where a Nintendo Power subscription was necessary to make basic progress.

GFX was nice to look at. There was a metallic facility theme across the map that never really out-stayed its welcome. Aside from some purposeful design symmetry no two rooms were ever the same, even if they utilized the same tileset.

Was good to see the Opposition suits make a comeback. Charge beam animation was gorgeous.

Really loved the custom soundtrack. While I always appreciate when a hack includes custom music, it's even more impressive when one of the authors is the composer.

Had a few minor gripes I won't go into too much detail here. Most the bugs I encountered were patched out in 1.08, and when I switched over to that version my life got a lot easier. There was one particular artifact room I feel a certain custom mechanic made it a little too hard to exit from.

Mentlegen and Smiley made an amazing hack in a very short period of time.

Edit: forgot to mention the physics. Respin and Speedkeep make for a buttery smooth experience.

I usually don't gravitate toward this style of hack, but I had a lot of fun with this one.

- I'm a sucker for symmetry so the map really speaks to me, especially the top half: incredibly dense but also almost maze-like in the way the rooms connect, though the sameness of the room aesthetics and foreground/background busyness can be a bit frustrating after a while. This could really benefit from a newer-style map screen, but it doesn't detract too much from the experience.

- All new music and it's all quite good and fitting, I especially enjoyed the tweaked boss themes.

- Speedkeep, and lots of places to use it. This one is built to play fast.

- A couple of minor PLM/item indexing issues, but nothing serious. The final item count isn't fixed, I believe max collection is 66%?

- Antigravity was a nice little contest flex, though it doesn't really come into play much save for one of the final area keys. This isn't a bad thing, as anti-grav physics can overstay their welcome VERY quickly.

Overall this is a fun/casual quickplay, and is a go-to for me when I'm itching for a hack but only have 60-90 minutes to spend. 4.5 out of 5; give it a shot if you haven't already. Stats are PB IGT, since this is categorized as a race hack and all.
