Stop The Vuvuzela Java Game

You have to shut up The Vuvuzela Sound! The vuvuzelas in the 2010 World Cup have been annoying people all around the world. Finally the time has come to stop this noisy nonsense. Fire footballs at the fans playing vuvuzelas with your phones [NUMBER KEYS]. Try to hit as many fans as you can. If you misfire or not hit the fans 20 times the game will end.
