An idea to polish
I like the idea, but, as said in the author comments, this game will lag a lot, which is unfortunate, which makes finishing the third level impossible.
Obviously, the thing to improve would be the lag. Try calibrating it. Many games with "pretty paper"(full of debris) use it. Like this, the game runs at a very high framerate, and is forced to skip frames if performance is going down. It will look like lag, but all it will be doing is to try to preserve speed.
Physics could also work, sort of like the one in the Ball Revamped series.
4/5, improvement please.
