Theoretically, with enough ribbon and buttons and graph paper, you could make a physical version of this iPhone game. But why would you want to, when the game's only $2 and so much fun? [iTunes and Lite Version]
This game is kinda addicting. I bought the lite version tonight, and beat that rather quickly. Now I'm craving for more. However, I told myself I can't purchase any new games unless they have retina display and Game Center support. We'll see how long that lasts.
