Cliffhanger

A swarm of murderous hooties stands between you and the diamond atop Mount Gemstone. Climb the stepped mountain from its foot one foothold at a time; stepping onto anything but rock, whether the sky beside the mountain, the gaps between the peaks or the two crevices, means a fall. Two crocodiles walk the long ledges, and four hooties fly the slopes: one up the left flank, one down the right, one bouncing round the middle and one that chases you. A touch from any of them knocks you off. The bonus starts at 500 and ticks down, and if it runs out you fall. Reach the diamond to add the bonus to your score and climb the next, faster level. You have four climbers, plus one every 5,000 points.

Controls: The joystick on either controller climbs up, down, left and right, one foothold at a time. On the title, up and down choose and a button starts.
