So why don’t you join another contest, with a little twist? We have been organizing and handling the UniKnowledge contest in the last weeks and recently, the deadline has been extended to October 14. The UniKnowledge is all about learning, and teaching. You must submit a game, or a game prototype (it really doesn’t matter), with full-source code, and explain how you made the game. The best tutorial, commented source and organized project, will win.
