love it, however adds some credits that the user can restart if they want to from the level they made it too.

I am not sure how you are going to do this but here are a couple of my thoughts. Each user to your sight starts with say 10 credits and can earn more for completing a game, inviting friends, highscores and {INSERT OTHER}

You could also add fruit machines so people could gamble the credits and earn more to play on the games.
