Writhen

Two or three snakes, player 1 in red, player 2 in green and the computer in blue, crawl around a walled or wrap-around field leaving their bodies behind. A snake never stops, and running into a body, a block or the border ends that snake's round. Every move a snake survives scores a point, and the last snake alive doubles its round score. After the chosen number of rounds, the highest total wins.

The options set the players (player 1 against player 2, player 1 against the computer, or all three), the number of rounds, the tail length, the speed and speed-up, the border (off means wrap-around) and random blocks. The FIRE option decides what the button does: nothing, speed while held, hyperspace or skip (three per round), or leave spaces in your body. The speed is taken from the original's own timer, and the field is 28 by 21 cells to fit the screen, against the original's 40 by 23. Original title tunes were written for this version.

Controls: controller 1 is player 1 and controller 2 is player 2. The stick steers the snake; the button does what the FIRE option says. The menus are worked with the joystick.
