Machop at Work

This is one game that really “rocks” on the Game Boy® Advance. Help Machop bust some boulders as he tries to beat the high score each and every time. As the counter winds down, you have to break boulders as they fly at you from off screen, being careful not to get crushed by them. If a boulder does hit you, tough rocks – it’s game over!
