In a world where hearts are not just organs but literal sources of personality and identity, you play as a heart detective in the sprawling city of Cardiotropolis. After a mysterious theft of hearts from the town's influential citizens, you must navigate through bizarre scenarios, collect odd clues, and interrogate quirky characters. Each heart stolen alters the city's reality, creating dramatic shifts in personalities—a cheerful mayor becomes a paranoid tyrant, a shy librarian transforms into a flamboyant artist. As you uncover the truth behind the heist, you'll need to piece together the fragmented memories of the stolen hearts, confront moral dilemmas, and even decide whose heart you will choose to restore. Choose wisely, as each decision brings you closer to understanding the intricate web of love, selfishness, and deception that binds the community.
