Castlequest

Castlequest (known in Japan as Castle Excellent (キャッスルエクセレント, Kyassuru Ekuserento)) is an adventure/puzzle-hybrid video game. It was developed and published by ASCII Corporation in 1985 for the FM-7, PC-88, and Sharp X1. Additional versions followed in 1986 for the Famicom and MSX, and was subsequently released in 1989 for the NES in the United States by Nexoft Corporation. It is the sequel to The Castle, released in 1985 for the MSX, SG-1000, and other systems (though not the NES). Like that game, it is an early example of the Metroidvania genre.
