how to play?

You begin on the right hand side of your screen, heading left, while descending as the name of the game implies. To switch direction, tap the screen. Rather than making a curved turn like in Rally Legend, the arrow turns abruptly in a zig zag pattern. Each stage spans 500 points. The first and last 75 points (0-75, 425-500, 500-575, etc) are free of any obstacles. In between, you are met with two obstacles, pillars and squares. Touching them will cause an immediate game over.
