From the Blacksmith Games site:
Knock your rivals out of the way and win the tournament! You’re in control of boostball. Tilt your device left and right as you guide boostball past enemies and into the goal! Collect powerups to smash anything that comes in your way!
This isn’t your mother’s soccer, this is boostball!
Not ready to go for the tournament? Try your hand at the never-ending Training mode! See how long you can last!
Compare (or brag about) your scores worldwide with your friends (or enemies) with OpenFeint score integration.
You’ll never look at plain boring soccer the same ever again!
