Up the vines, as far as you can get, while the world throws things down at you. Rocks in the jungle, icicles on the snowy peaks, fireballs in the lava caves — each location has its own hazard arriving from above, and the monkey climbs at whatever pace your two keys manage. Bananas buy a second chance and a chili pepper buys a short rocket upward. Jungle Climber is a score game with no ending, and the honest measure of it is how high you got before you stopped paying attention.
