Knightmare II: The Maze of Galious 1987

Is it still worth playing?

Popolon and Aphrodite return to Castle Greek to free their unborn child from the evil priest Galious in this 1987 action adventure for the MSX. You can switch between the two at any time: Popolon breaks boulders faster and has a variable jump, while Aphrodite fires more projectiles and jumps a fixed height. The castle works as a hub, like an overworld, with entrances to ten hidden worlds, and items found in them open new areas. Each world ends with a boss called a Great Demon, which you summon by typing the incantation read from a gravestone. A password saves progress. The structure of items opening the way later inspired La-Mulana. The hub is open from the start and items decide where you can go next, so finding the way still takes exploring.
