Crazy Climber — About this game
The Famicom version of ``Crazy Climber'' is a unique single-player action game where you move your left arm with Controller I and your right arm with Controller II. Hang your hands on the window frame and alternately raise and lower your hands as you aim for the top while enduring obstacles such as signboards and flowerpots. In the hidden rooms of each stage, the operations will change from the normal screen, and items such as keys, watches, and invincibility medicine will also help you conquer the game.
