I understand that it needs to be a more complete game if we're going to do the "make graphics for a game" challenge. I was simply offering art in motion though, so if we need more than that to make that particular challenge work, I suggest we look for some other programmer interested, since I really can't free the time to do a game engine, even basic, just for the sake of a challenge.
Maybe we should look into getting help from GDR or Game Maker community. A crossover collab could be tons of fun. I'm sure that the Ludum Dare folks would be up for something like this too, since they are used to making a quick, fun game under a time limit.
