Very neat and creative concept for a platformer, the need to put yourself in danger in order to change the level design was really cool, reminded me of the Mirror Temple in Celeste. The controls felt a little sluggish (but I suppose you play as a slug so that makes perfect sense actually), and it made more precise platforming a bit frustrating when it feels a bit like trudging through thick water. That said, it has lovely art, and very neat mechanics. There's definitely something very cool here.
