In 'Whose Shadow Is That?', you play as a once-renowned detective turned reclusive artist who starts receiving anonymous letters that hint at an unsolved murder from their past. Each letter gives you a piece of a shadowy photograph—images of figures from that night who were never identified. As you delve deeper into the mystery, your psyche begins to unravel, leading you into a series of mind-bending interactions where your perceptions of reality are constantly questioned. Using a mix of deduction and choice, you must confront both your past and the shadows that haunt your studio, unraveling connections that challenge your understanding of truth, memory, and the shadows of guilt.
