this looks kind of neat, and it's fun at first, but it's not worth $15. there's no way the author put $15 worth of work into this. it should be free. i'd probably play it if it were, but it's not worth paying for.

also, only being able to play 3 levels is not going to make me pay, just make me delete the game.

good luck in the future, it's a nice beginner's project.
