Shoot Them All

In Shoot Them All you have to hit objects that move around the screen with your wall mounted cannon. Since you are not able to change the position of the cannon or its aim, you have to rely on great timing and anticipation. If you don't hit the moving object you will lose the game right there and then. But, even if this tempts you to just wait a little bit longer and aim even better, you will have to fire rapidly or you will lose anyway when your projectile finally drops to the ground.
