In 'Whose Heart Is It Anyway?', you awake in a bizarre city where emotions are physical entities detached from their owners, and you're left with no memory of your identity. As you navigate through surreal landscapes filled with personified feelings—such as anxiety, joy, and envy—your goal is to piece together the story of your heart. Each emotion interacts differently with the environment, guiding or obstructing your progress. You must collect emotions, confront your deepest fears, and solve intricate puzzles that revolve around relational dynamics. The choices you make influence who you become and what kind of heart you ultimately reclaim, leading to multiple endings based on your emotional connections and the relationships you form along the way.
