Ghost in the Sheet is a paranormal comedy adventure in which you play a ghost investigating a mystery. It also features two short optional arcade subgames. The main game is played from a first-person viewpoint, and presented in a slideshow format. It contains dark humor and a unique paranormal skill system.
The game begins at the end of the character's life - unfortunately, the afterlife isn't quite what you expected. You must master new paranormal skills - you weren't successful in life, now you will struggle to be successful as a ghost. You must now wear a sheet and work for a horrible boss. You do not have normal human skills, but must learn new ones (such as activating levers and directing a light beam) as the game progresses.
The Sector Omega factory has been left deserted following a fire, and only the ghosts of its inhabitants remain. Could there be a monster lurking within? To solve the mystery, the player must explore the remains, interact with machines, and look for written and audio clues, ranging from pattern puzzles to writings.
