In 'Whose Shadow Is That?', players step into the shoes of a paranoid detective navigating a surreal city plagued by vivid nightmares and distorted realities. Each day, the detective receives anonymous tips about a series of bizarre occurrences tied to shadows that seem to have minds of their own. As players uncover the truth behind each shadow, they must solve cryptic puzzles, engage in tense conversations with eccentric characters, and make morally ambiguous choices that affect the outcome of their investigation. The line between shadow and reality fades as the detective begins to question their sanity and the motives of those around them, leading to multiple endings based on players' decisions.
