Paintball is a simple time waster that should prove a fun diversion for an hour or two. Or three. The playing field consists of: a ball, which drops under gravity and bounces; a square, which the ball is trying to reach; pre-set platforms which the ball will roll/bounce on; and custom-made platforms which you draw freehand on the screen. Simpler than some games with this feature, Paintball is unlikely to elicit gasps from its players with advanced physics, but what it does it does very well.
