i love the idea and visuals for this, i wish it didn't start me at the beginning every time i fell through the stage because it happened quite a lot
it's also a bit hard to judge just how far / high i can jump and where i can squeeze through, but with some more time and polish this could be even more fun ! great job !
i'm assuming the sketchy outlines is a shader, as someone who's just learning to make them, very impressed :]
