The object of the game is to control both the Blue and Red balls, but don't let them touch. However, if you can get them close without touching, you can activate the Close Call! for more points.
The arrows point towards the mouse, and push all the balls on the screen. Keep the blue ball from touching any red balls, or you'll lose a life. If you can get them close without touching however, you'll get extra points for a close call.
