Cratermaze

Cratermaze is an action game developed by Hudson for the TurboGrafx-16 and published by NEC in 1990. It was originally published in Japan as Doraemon: Meikyuu Daisakusen (ドラえもん 迷宮大作戦) by Hudson in 1989. The game was re-released by Hudson Soft for the Wii Virtual Console on August 13, 2007 in North America, and on August 17, 2007 in Europe and Australia.

The game was originally intended to be an arranged port of the arcade game Kid no Hore Hore Daisakusen, but the main character was replaced with the licensed anime character Doraemon, a blue earless robotic cat from the future. The story was altered to be about Doreamon and his four human friends who go time travelling, only for his four friends to get kidnapped,forcing Doreamon to rescue them all and bring them safely back home. When the game was converted for play internationally, the anime license was removed, and the original player sprite from the arcade game was restored, but a similar story line was left in place.

Cratermaze is a top-down maze game in which the player must run around a maze collecting items while avoiding enemies. Finding all 16 treasure chests reveals a key to the exit somewhere in the maze, which the player must reach before they can move on. New items and power-ups become unlocked as the player progresses in the game, and need to be grabbed along with the vital collectibles.
