Played it, cleared it on the third try, about 24s. Then I poked the build. Two things stood out.
The collapse pressure is the good part. The second you notice the floor behind you is gone, you stop playing safe. That read lands.
1) The page says "you auto-run to the right". It doesn't. You only move while holding right or D. Someone who reads the page and taps space stands still until the wall eats them. gengar-shark hit the same wall above. Either make the auto-run real, or put "hold right to move" on the first platform.
2) The collapse wall never catches a running player. EAT_SPEED is 240, run speed is 330, so the wall is always losing that race. It only kills you if you stop or miss a jump, which makes "the collapse eats everything" decorative and turns the whole level into one-mistake-and-done. If the wall is the threat, close that gap.
Difficulty itself is fair: 7 clean clears out of 8 tries, ~25s each.
Swap? Mine is RIG, 2 min, one mechanic: drive to a part, bolt it on; every part changes both how you move and how you live. https://broilands.itch.io/rig Play it cold, no explanation, and tell me the exact moment you got bored. Raw beats polite.
