Cratermaze is a variation of the Japanese games Booby Kids (released for Famicom) and Kid no Hore Hore Daisakusen (1987), an arcade game released by Nihon Bussan.

A number of contemporary reviews compare the maze-like gameplay to Hudson's Bomberman series.

[2][3] In the game, the hero Opi (Doraemon in the Japanese version) is traveling through time with four of his friends when they are captured by the villain Zenzombie.

He travels through various eras in time (modern, samurai, future, World War II and prehistory), collecting treasure to open doors to the next era, and kills enemies by digging holes and burying the enemies.

In the Japanese version, Doraemon replaces the titular character Opi, while Opi's friends are replaced with other Doraemon characters.
