Puzzle-adventure where you guide four teens trapped in a derelict mansion stalked by a blue monster. You control Hiroshi and his friends as they search rooms, solve environmental puzzles, and dodge the creature hunting them. The game splits focus between figuring out locked doors and hidden passages while managing your group's positioning—get caught and it's over. Each character handles differently during exploration, affecting how you approach obstacles. The mansion's layout opens gradually as you find keys and trigger events, with the monster's patrol patterns forcing you to memorize routes and time your movements. Expect trial-and-error deaths as you learn what works. It's built for players who don't mind repeating sections to optimize their path through a single contained location under pressure.
