Once you understand the game, this is actually an interesting puzzle.
The interface could use a little work though. Just little touches like, when you click on the credits or help screen to return to the game, if you click in the same place that a button is, the button registers as pressed. So you have to click the help or cred button, then go click in the upper right corner to avoid this problem.
To solve this in code, just ensure that the player goes through an entire touch down + touch up cycle before activating a button.
Anyway, once you figure out how it works it's playable. I'm going to try and beat it in 5 guesses now...
