This is an arcade style game. You shoot at balls that fall from the top of the screen. You control a ball that rolls back and forth at the bottom of the screen. Moving also aims your shots which is what makes this game unique.

Use the arrow keys to move left and right and to aim. Use the spacebar to shoot the balls. Shoot each ball twice to destroy it. Destroy the specified number of balls to pass each level. If all 10 levels are completed, a bonus round commences in which you can score one point for each ball destroyed, but it is instant gameover if you miss a ball.
