Obstacle 128

Two players each steer a line that never stops moving. The border is drawn in the players' colours, purple along the top and right and blue along the bottom and left, with a gap at the top of the left side and the bottom of the right side. Each round both lines start on the middle row heading the same random way. Push the stick to turn; holding a diagonal or centring the stick keeps the direction. Running into any line or border, or out through a gap, is a crash, and a crash scores a point for the other player. If both crash, both score. A new round starts by itself, and the first player with at least 5 points and ahead wins. In a one-player game the computer steers purple. Three speeds are offered.

Controls: Controller 1 steers blue and controller 2 steers purple; in a one-player game the computer steers purple. On the title, left and right pick one or two players, up and down set the speed, and a button starts.
