Ironically, it shares a lot of DNA with the Kinect’s major competitor, the Sony Move. You have these blocks of different colors, which place on the floor (or a table or whatnot), and which correspond to different gameplay elements: a guy has to get from here to there, and needs stairs, bridges, and so on placed in his way. It’s like Lemmings crossed with… Gyromite, maybe? I don’t know. But it looks fun and frantic and hey, it involves big colored blocks.
Right now it’s just a prototype, but it’s entirely possible we’ll see this as an XBLA release sooner or later. Here’s hoping they get a little funding and make it into a proper game.
