In a world where hearts are more than just organs, players take on the role of a quirky heart thief called Mortimer, who inadvertently steals the hearts of various eccentric characters during a chaotic art heist gone wrong. As Mortimer, you must navigate through a vibrant city divided into districts controlled by different emotional themes—joy, despair, love, and rage. Each heart you collect grants you unique powers, but you must also navigate the consequences of your choices, leading to hilarious and dramatic interactions with the characters whose hearts you’ve stolen. Will you return the hearts for a chance at redemption, or will you keep them to harness their powers and create an emotional masterpiece? The fate of the city—and your own heart—hinges on your decisions.
