The first player controls Popo, a boy wearing a blue Eskimo parka, while the second player controls Nana, a girl wearing a pink one. The only tool they carry is a wooden mallet to carve openings in the ice above and to club enemies. Each mountain level consists of eight layers of colorful ice and a bonus stage. Standard, dull ice blocks pose no threat other than an easily disposed-of barrier and platform. Square ice blocks with higher detail are indestructible, forcing the player to take another path. Hatched ice acts as a conveyor belt sliding the Eskimo either left or right. Finally, many mountains include unbreakable moving platforms resembling clouds. The bonus stage takes place at the peak. Within a 40-second time limit and no enemies, the Ice Climbers often face trickier jumps and multiple moving platforms. The peak is also the only place to recover stolen vegetables, most notably eggplants. Collecting just one piece of corn from the fifth bonus stage is the only way to gain an extra life. At the top of the peak, the Condor flies overhead.
