You get to play as a little light bulb that runs around town. Its job is to cross a road full of cars. The cars drive irregularly and sometimes you can skip between them. If you get hit by a car, the light bulb will break and you will have to replay the game. There is no quiet section in the game, even in places where there are no cars, you may get run over by another vehicle, such as a motorbike. So you have to act quickly and very carefully. your task is to go as much of the way as you can. There is no ending as such in the game.
