The goal of the game is to control your marble in order to get close to bright and colorful stars placed around the level and then let your zapper do the talking. The more stars you zap, the more points you get. Each level has a certain amount of points you need to get in order to complete it. The more points you gather the bigger you grow, and the harder you are to be pushed around by physics contraptions that you'll encounter such as jumppads, air vents and vortexes. The downside to this is that your own weight will slow your jumping down, making some places unreachable after growing too much.
