THE WALL For every wall successfully scaled points are awarded, but on each there are forces of spritely adversaries poised to attack -archers, dragons, witches on broomsticks and multi coloured cannonballs, just to mention a few. Before attempting to bid for freedom you need to study their moves carefully. On each screen the attackers and the way in which they travel are different. A collision loses a life, but for every 500 points there's a bonus life. Control is from keyboard or joystick. You are unable to start until the alpha lock is up.
