In a world where people's hearts are detachable and can be swapped, you play as Max, a heart collector with a knack for getting into messes. When you wake up with an unfamiliar heart in your chest, you must navigate a city filled with bizarre characters and race against time to uncover the heart's former owner. Engage in choice-driven conversations, solve puzzles that reflect the emotions of the characters, and confront your own emotional baggage in twists that will keep you guessing. Every decision alters the outcome, from friendships to betrayals, as you learn what it truly means to be 'heartless' or 'full of heart'.
