In a world where shadows have a life of their own, players assume the role of an amateur detective who specializes in shadow crimes. Each shadow holds secrets of its owner, and players must navigate a series of shadowy encounters, puzzles, and dramatic events to uncover the truth behind a mysterious crime that only involves shadows. Choices matter immensely as players decide whom to trust—friends, enemies, or their own shadow, which may or may not be hiding the truth. The narrative shifts based on the decisions made, leading to multiple possible outcomes, some of which may twist the players' perception of reality itself.
