Pointless.
It seems like there's no sort of scoring mechanism to this game. In addition to that, if I'm not mistaken, there isn't any sort of animation or even sound to indicate when you've actually shot one of the stickmen. They move far too quickly, but nothing happens one way or the other, if you do shoot them or don't. I can't help but think that, if you'd spent 25 minutes on this game, it might be a bit better. It shows promise and would be less frustrating if you labeled it as a demo rather than a game.
