Famicom Mini Vol. 22: The Mysterious Murasame Castle (Nazo no Murasame Jou) is a fast-paced action-adventure originally released in 1986. Set in Japan's Edo period, players control the samurai Takamaru on a quest to infiltrate five castles possessed by an alien force. Unlike its contemporary, The Legend of Zelda, Murasame Castle focuses on high-speed combat and projectile management rather than puzzle-solving. This GBA re-release allows modern players to experience a hidden Nintendo gem that influenced the Dynasty Warriors series and features a protagonist who has appeared in Super Smash Bros.
