Pros: Offers an unexpected play experience that will have players' heads scratching.
Cons: Could be a bit longer and less like a halfhack. No animals to save.

Don't waste your time with this one.

Hack is incomplete. Most of the edits are early on in Brinstar with the entirety of Crateria/Norfair/Ridley untouched.

Utilizes a large amount of required wall-jumping, IBJ, and even a camera trick (you have to follow your long beam shot via morphing ball to exit the route you entered the room in since the top exit is sealed.)

Uses questionable placement of invisible walls and making certain areas unreachable. There was also one instance of actually making the hack easier by allowing a Super Missile tank in Brinstar to be accessed with bombs instead of Speed Booster + High Jump.

Hack cannot be finished because the game crashes upon entering the door transition to the elevator room to Kraid.

I don't know how item % is calculated for multiple pickups so my final tally is below.
Ended at 160 Missiles, 12 Supers, 7 Energy Tanks. Items: Long Beam, Charge Beam, Ice Beam, Wave Beam, Unknown Item #1, Bombs, Varia Suit, Unknown Item #3, Morph Ball, Power Grip, Hi-Jump, Screw Attack.
