As for the game itself, it's exactly the kind of thing that's very popular among the huge tween audience for Facebook games -- there's a cartoonish avatar that can interact with friends socially, and checking-in to certain places earns the avatars popularity and status. There's a microtransaction element as well -- interacting uses energy, and if you don't want to wait for a refresh, you can spend 99 cents to get more. Standard social gaming stuff, although Booyah is pretty good at putting it together by now.
Booyah remains a company to watch in the social gaming space -- it doesn't seem to have had quite the success it wanted on Facebook, but the company is flexible enough to switch a game like this over to Apple's platform without skipping a beat. We'll have to wait and see whether or not the free app gains MyTown's level of adoption, however.
