Classic NES Series: Ice Climber

As Popo, players use a trusty mallet to work their way up the mountain.
They chip away at the blocks overhead, then jump up through the
resulting hole to the mountain's next level. Once Popo reaches the top
level, he enters a fast-moving bonus stage in which he can pick up
veggies and, hopefully, reach the summit for a big point payoff. Of
course, not everyone's supportive of Popo's pastime. Toppies fill Popo's
holes, so players must jump through the gaps quickly. It's easy to slip
off some of the icy levels, as Polar Bears, Toppies, and other ferocious
fauna don't want players up there. There are 32 challenging peaks to
scale. How will you fare?
