Bang Bang Ball is a puzzle game based on Metro's Mouse Shooter GoGo. Player 1 controls a mouse on a skateboard and player 2 a mouse on roller skates trying to rescue their girlfriend who has been kidnapped by a bunch of cats. The gameplay remains largely the same - throw colored balls at matching balls of the same color to clear the stage. Unlike the first game though there's no button to lock direction, instead there's a 2 player co-op mode (Mouse Shooter GoGo only had a 2 player versus mode). Also, collision with the balls diminishes player's health, in the original game you needed to restart the stage if you were hit once, this game has a life bar (2-5 hits depending on the DIP switch settings).
The Korean version called Battle Bubble retains the same gameplay, but has different backgrounds.
