Fun Fact: The characters from Ice Climber appear in the Super Smash Brothers games.
Ice Climber was a launch title for the NES. Players had to ascend a mountain and use a wooden mallet to break rock or ice chunks or smash enemies who were in the way, both of which scored points, while also navigating moving platforms.
At the top of every mountain was a bonus level where players had a limited amount of time to grab items for extra points and then hitch a ride on a passing condor to the next stage. If they weren't able to complete the task in time they still went on to the next stage, but didn't get any of the bonus points.
