As the protagonist navigates through a series of interconnected stories, they must unravel a dark mystery involving a secret society that manipulates emotions through these shadows. Using a unique dialogue system, players gather clues, confront characters, and make choices that influence the shadows they perceive and the outcomes of each case.
