Escape room horror puzzle game. You wake up after a sound sleep and find yourself in a madhouse. You see your photo on a casebook, your information in a folder. Is it truth that you behold? The door is locked tight, the window welded shut. Your shadow wavers in the flickering light. Is it an illusion that you behold? Can you finally find out the truth and escape from the Madhouse?
