I developed the prototype of this game at MIT in January 2013, where MakeGamesWithUs was helping to teach a one month course / competition on iOS game development. After the course, they offered for me to publish the game with them in exchange for revenue sharing. It's come full circle, because now I'm working for MakeGamesWithUs as an instructor for their summer academy course. The course isn't discounted if you choose to publish with them, but they can provide their SDK, art, design advice, and help with publicity.
