Door Door

Door Door is a Japanese-developed computer puzzle game designed by Koichi Nakamura and published by Enix. As Enix's debut title, Door Door first released in February 1983 for the NEC PC-8801 and was subsequently converted for other Japanese computers. The game's success prompted a Famicom port and an expanded edition in 1985 and a mobile phone release in 2004. In 2006, editors of the popular Japanese gaming magazine Famitsu placed the game among classics such as Super Mario Bros. and Donkey Kongin its listing of the best Famicom games. Despite its popularity, Door Door has never been released outside of Japan.
