Really fun game, I loved the crazy physics! For some reason, the audio doesn't work (and I remembered to use Chrome, so I don't think I'm doing something wrong). I think the levels are too similar, I would appreciate some more variety. Additionally, if I get trapped by enemies, it's pretty much game over (would appreciate a moment of invincibility after getting hit). Also, a lot of the art looks blurry, did you import them correctly? Finally, I feel that the colors are too bright and vibrant, and don't go great with each other (I would recommend using Adobe Color to get a nice palette).
My favorite part of this game is (for some reason) randomly getting flung across the stage. You'd think that that would be a bad thing, but it's so much fun. I hope, if you continue with this idea, you utilize that feature more.
