So this one went from 'OK this is a little weird, but pretty standard stuff', to 'this needed some more playtesting' to 'ohhhhh, how clever!' in a few short minutes. Super creative concept here.
I did run into what I think may be a bug, which is funny in this context:
I mouseclick-moved, 54 69 75 6e 64 65 72'd, and Dead'd my way to level 3 in the endless glitch slime error track for a good 15 minutes, but nothing was happening. I tried every menu option, every battle option, even ate some Asparagus in a glitchslime fight, all to no avail. Finally I thought, "Maybe the next thing is tied to keyboard-controlled movement input somehow?" I began moving around using the arrow keys, and was shortly thereafter rewarded with the conclusion, moments away from deciding that the loop must be the ambiguous, ultimately pretty fitting conclusion to the story :)
