This game makes me feel stupid.
It would be nice if the strength of the launch wouldn't just stay maxed out, and instead slide from weak to max and back to weak, like many other games. Somethings don't work, like the levels where it's pretty clear that you have to purposely launch balls from miscolored buckets in order to get to the right color -- the ball won't launch quite right and it has to be done again, or even restart the whole level. A few tweaks and a few more levels, maybe even a level editor, would make this game even better.
