I think a game which shows glitchiness with corrupted graphics might want to pick a jam where it gets more screen resolution to play with, since it's hard to tell whether a thing looks wrong because it's "corrupt" or it looks wrong just because it's hugely-inflated pixel art :) Anyway, basic gameplay seemed fine, but I never grasped whether there's a point other than "keep killing the monsters until eventually you die". I thought that the "green arrows" which appear were telling me a direction to go, but now I think that they just sometimes appear when I kill a monster, and I don't know why. In short, a good proof of concept, but it needs a lot more before it becomes an actual game.
