Slither

Published in Ahoy! 1985/11 (Issue #23). Got fast reflexes? Then Slither is for you. The object is to collect prizes from the 40 rooms of a deserted castle by maneuvering the snake and avoiding walls and the snake's tail, which grows continuously (use a joystick in port 2). Collide with either, and you lose a life (you start with seven). If you succeed in gulping down the prize, you move to the next screen; the screens get more difficult as you go along.

After you complete a screen you get a bonus which is the same as the value of the prize on the next screen. If you complete all 40, you get a bonus equal to the sum of the values of all 12 prizes.
