Crazy Climber

The player assumes the role of a climber attempting to reach the top of four skyscrapers. The climber is controlled via two joysticks, which control his respective four limbs. Windows open and close to hinder the player's progress, so do obstacles such as falling objects. The game ends when the player is unable to catch onto windows and falls to his death.

Crazy Climber was designed by Shigeki Fujiwara of Nichibutsu, who would eventually create the Bomberman series for Hudson Soft. The player character was intended to be followed by a wall of fire, but was rejected by Nichibutsu. Programmers at Jorudan, including Toshikazu Sato and Kyoji Oda, were handed storyboards of the game design to work on for 5 months, with little assistance beyond quality control. Frustrated by not receiving credit for their work, they added an easter egg where if the player enters their initials as "JORDAN.LTD", it immediately turns into "JORDAN" while giving the player 2 extra credits as an in-joke. Nichibutsu never found out before players discovered the easter-egg, and Jorudan had cut ties with them at that point.

In Japan, Crazy Climber was the third highest-grossing arcade game of 1980, just below Pac-Man and Galaxian. Crazy Climber was also Japan's eighth highest-grossing arcade game of 1981.

In North America, Crazy Climber was among the top ten highest-earning arcade games in the summer of 1982.

In 1981, Bandai Electronics manufactured a hand-held VFD version of the game. A board game was released by Bandai in 1981, exclusively in Japan.

A 1985 sequel titled Crazy Climber '85 was produced, but it was put into storage by Nichibutsu in favor of Terra Cresta. This unreleased sequel was eventually included in on the PlayStation version of Nichibutsu Arcade Classics.
