Mountaineer Mack

Mack climbs an endless forested mountainside, walking left and right along the slope and scrambling upward, and the mountain scrolls down beneath him, 20 feet a row. A boulder tumbles down from the top all the time, and the slope holds a campfire, pairs of pines, and a bear or a snake. Touch any of them and Mack slides all the way back to the foot of the mountain and loses a man; he has three. Mountain n is n thousand feet high. Near the top the dangers stop, and Mack walks onto the snowy peak and plants a flag. After six mountains the boulders fall faster.

Controls: The joystick (either controller): left and right walk, up and down climb. Either button continues at the top of a mountain.
