Door Door is a puzzle platformer released exclusively in Japan on July of 1985 for the Famicom. It is perhaps best known as Enix's first ever video game, as well as starring the protagonist Chun, whose name would go on to appear in the title of developer Chunsoft. The game has the player character being chased by aliens traveling in pre-determined paths around various platforms. The goal of the game is to have one of the aliens pass through a door and then shut it, thus preventing it from chasing your character for the rest of the level. The game was credited by Famitsu as one of the greatest Famicom video games.
The name of the game's main character, Chun, was implemented in the name of the creators' company, Chunsoft.
Door Door was the first Enix published title.
It was among the many titles listed in Famitsu's best Famicom video games.
