I don't get it. The physics are very wonky, which is why I assume the ball is crazy?
I feel that there should be some indication that the purple things kill(?) you in the first level. Additionally, the enemies(?) that follow you in the last level should look different than the purple things that kill(?) you, as well as not following the player so close that they stick to you like magnets, as it makes the level a lot harder to complete. Also, the game should indicate to the player in some way that they've completed the game, (or at the very least, go back to the menu) instead of just starting from the beginning again.
There's also no secrets or paper related theming, so that's disappointing.
