The Maze of Galious

The player controls Popolon and Aphrodite, entering the evil priest Galious' castle to free their yet-to-be-born son Pampas from the priest's evil clutches. Being able to control Popolon and Aphrodite means the player can switch between two characters that have slightly different abilities. For example, Popolon can push stones and open heavy doors. On the other hand, Aphrodite survives longer under water and she can shoot more projectiles. Should either character die, the other can visit a shrine and pay for resurrection. Unlike typical platform games, both characters can survive some damage as they have hit point bars.

The game has several types of enemies, each with strengths and weaknesses. Some monsters are immune to frontal attacks, some are more vulnerable to fire and so on. Ten different bosses are to be fought too. Defeating a boss will give the player a key that is used to unlock doors to other boss areas. In-game saving is provided by giving player an encoded password.

The Maze of Galious offers extra content if The Game Master, Knightmare or Q*bert are inserted in the second cartridge slot available on some MSX machines.

A Family Computer version of Majō Densetsu II was released exclusively in Japan a few months after the MSX release. The Famicom version, titled Majō Densetsu II: Daima Shikyō Gariusu (魔城伝説II 大魔司教ガリウス, Demon Castle Legend II: Great Demon Bishop Galious), is a completely redesigned version of the game.

La-Mulana is a homage to MSX games in general and The Maze of Galious especially,[2] and borrows many elements from the game. It also contains a bonus area designed to look like a The Maze of Galious level, in which the MSX cartridge of the original game can be found as an in-game item.
