Play Ayakashi no Shiro Online
You creep through a demon-infested castle as Nobunaga’s ninja, freezing yokai with mystic arts or vanishing when fights turn ugly—every dark hallway’s a gamble. Those rare floor maps feel like lifelines in this maze of cursed corridors.

Ayakashi no Shiro came out for the Game Boy in 1990, developed by Irem. It was part of that early wave of portable action-adventure games, where developers were still figuring out how to translate deeper, exploration-heavy experiences to the small screen. The game doesn't have the immediate name recognition of some contemporaries, but it carved out its own niche with a distinct setting and a focus on stealth.
You control a ninja on a mission to infiltrate a castle overrun by supernatural creatures. Your main goal is to find and defeat the demon lord, which involves navigating a multi-floor dungeon, room by room. A key mechanic is your ability to use ninja magic to temporarily freeze enemies, letting you bypass threats instead of engaging in direct combat every time. You also collect scrolls to learn new spells and search for keys to unlock doors, all while managing a limited inventory. The pacing is deliberate, almost methodical, as you carefully plan each new screen to avoid being overwhelmed. It feels tense and thoughtful, like a cautious dance through a house of horrors where every wrong move has consequences.
