I couldn't get past the third level. It's a shame because I would've liked to see more, the concept sounds really fun. I found it too hard because I can't figure out what stops me and what doesn't, what the hitboxes are, and I don't really have time to look at the level before it starts, so it feels like you just have to pray that you won't hit anything.
I can give you full score on visuals and sounds though, very high production quality for 4 days.
