Contest Rules?

This following paragraph doesn't sit well with me.

You agree that if your game is selected, it will be published under this agreement. If you are a minor, your parents must consent to your submission and consent to your game being published under this agreement for minors. In short: MakeGamesWithUs will take the first $1000 in post-Apple revenues to recoup certain fixed costs. You will then receive 70% of post-Apple of revenues thereafter.
