The game was built on the cocos2d engine. As Keith mentioned, it definitely had some quirks, but I really couldn't have asked for a better starting point. I should also mention that we're somewhat stuck with Cocos2d v.7, which is basically a beta build. It works well enough for our purposes and the upgrade process would be drastic and error-prone enough that we may as well stick with it, but the recently released .99 is better in just about every way, from what I've seen and heard.
