In version 0.0 I said you should make your cursor a darker ball, make the game easier and decrease the number of enemies, and since you have done all of that I'll rate it a 4/5.
I think it needs a cursor and not just the standard arrow. It should start with less balls, and they shouldn't build up speed so fast because right now I simply suck at this game. The gravity thing is okay because it makes this game a little different to particles.
