I played this game back around 1999 or so, although I'm not sure if the game is older than that. From what I remember I controlled a male character and tried to collect different sized and colored balls on the board. The balls bounced around the screen. I can't remember much else, but if I think of anything else, I'll edit the post.
Edit: Sorry a little bit more info. I think the first level starts out with one large ball and then when you touch it, it breaks down into two smaller balls, and then you touch that and it broke down again. After it got so small it just disappears. If i remember correctly the ball was green. I think the rainbow colored balls were some special ball that gave you some sort of power up.
