Washman is a detective puzzle game that combines micro horror and realism themes. You will play the role of a "house cleaner" hired to go to a mining site that has been shut down due to a supernatural event, uncovering the terrifying truth buried deep underground. By picking up scattered old photos, you can trace back to the memories of the deceased before their death, experience the last moments of their lives, and unravel the threads to deduce the truth.
