A Puzzle Adventure Like No Other
In this unique blend of puzzle-solving and horror, every item you collect transforms into a polyomino-shaped piece. Use these pieces creatively: solve intricate puzzles, craft tools, unlock paths, or even sacrifice them in moments of desperation. Adapt your strategy and make the most of your inventory—how you survive is entirely up to you.
Face Undead Warriors with Iaido Precision
Explore a haunted samurai residence, where restless spirits of fallen warriors still roam. Engage in intense one-on-one encounters using finely tuned Iaido sword techniques, timed dodges, and parry counters. Overcome fear through skillful slashes that break the tension and offer moments of exhilarating relief.
