In this game you control a cannon located at the top of the screen. Below on the screen there are blue and red balls — you need to shoot and destroy the red balls. You can also destroy blue balls to earn more points, but your main goal is the red ones. At the bottom of the screen a platform moves back and forth. If the ball you shoot hits it, you will earn an extra shot. You lose if you run out of shots, so count them carefully and try to score as many points as possible!
