Here's a quick trailer of a game coming "soon-ish" on the App Store called Button Brigade. As the video explains, you play as a worm and are trying to escape the factory where you were built. Why? Because you're a robot worm, of course. Your robotic snake self has all sorts of cool abilities including but not limited to time travel?
From the looks of it, they're in their final phases of testing right now. Keep an eye out for Button Brigade whenever that's done, plus or minus two weeks for Apple approval. For more details, check out the Button Brigade web site.
