How does this game play?
With the left and right hand to control the left and right 2 cars, round can eat, square can not eat, although this game looks very simple, but the actual play, you will feel your left and right brain, and your Left and right hand, together is not very comfortable, flexible operation, fun game, quickly to challenge, exercise your left and right brain, play it, see how much your ability to challenge your glory ~!
