A Tron suitable for iPhone is already cool in itself, but this multi-player version is incredibly cool: a line of vertical separation sharing the screen in two, allow you to find an opponent on a single screen. We must work to Pancakes of Japanese developers, which also offer music apps rather nicely done.

The game is called Bike Light, and is not yet on the App Store, but will be soon, with a free version with a single player and multiplayer paid version (which will also be playable with up wife four players on two phones).
