A very interesting concept
At first I tried very hard to be strategic, ricocheting balls into each other that sort of thing, but then I got bored and decided to just rapid fire.
I beat my high score of like 30 (strategic) by about 150, just pressing the button over and over again.
My point is that strategy really didn't help me much.
It would be a lot easier to be tricky if there was away to bounce the balls back up, instead of just letting them slip past the point of no return.
All in all a god game, though.
