One of quirky Japanese company Nichibutsu's best-known games, Crazy Climber sends an urban adventurer climbing up a series of skyscrapers, dodging open windows, dropped objects, birds and other dangers on his way to the top. The control scheme consists of two joysticks that move the climber's hands independently, requiring you to coordinate your movements to climb and move horizontally to avoid obstacles. In addition to its novel control scheme, Crazy Climber was unusual for its sampled voices (saying "Go for it!" and "Oh nooo!"), and its simple concept and challenging gameplay led to a sequel and numerous computer game clones.
