The game is a bit off. The screen effect is cool, but when combined with a very high contrast visual at the start, it isn't really good to see.
The collision is really weird (I cannot jump when my face is in the box), and the movement is so stiff (maybe it's because I am a raccoon?)
The vent section is really confusing because I don't know if I should move or not (Plain repetitive background + Slow movement).
Anyway, cool game.
