As many have said above, this romhack is one of the best.
It has a clear concept that is wonderfully implemented through the mechanics of Super Metroid.

You can play this quicker with save states, but I found it quite fun and challenge to map out the cube by hand and try to find the right path out in one try. It's much harder but much more rewarding - I recommend it!

--very minor spoiler / advice warning--
Two pieces of feedback for the creator/advice for the player:

a) The only room with a name in the hack is a little misleading, I believe a (?) could help new players not give up and reset. I'd call it "Infinite Room?"

b) Once you find how to deal with "Infinite Room?" do not go back the way you came - it glitched my game and soft-locked me - no fun. I assume it's too hard to fix directly so making that path one-way would be an easy fix to prevent encountering the glitch.
