DOOR DOOR mkII

Door Door mkII is an action game developed by Chunsoft—the studio later renowned for the Dragon Quest series—and published by Enix in 1985. Serving as an expanded version of the original Door Door, this title features the original 50 stages plus 50 all-new levels for a total of 100 challenging stages. Players control the protagonist, "Crazy," and must use strategic thinking to lure enemies into doors to trap them. It stands as a classic hit from the dawn of the Japanese computer gaming era that captivated many fans on platforms like the PC-8801.

The protagonist, Chun-kun, must escape from monsters like the Namegon and Otapyon, each of which pursues the player with its own individual artificial intelligence. The player's goal is to skillfully lead these monsters and trap them inside the doors scattered throughout the stage. Clearing a stage requires capturing every monster, allowing the player to advance to the next set of challenges. Despite its cute character designs, this is a demanding action game that requires careful observation of enemy behavior to master.
