In "Whose Heart Is It, Anyway?", you play as a mischievous heart thief in a surreal world where heart replacements are a social norm. Your goal is to collect 'hearts'—not just any hearts, but ones with unique emotions tied to their previous owners. You navigate a series of absurd and entertaining scenarios, interacting with quirky characters whose hearts you steal, aligning with their outrageous personalities and problems. As you ping-pong between morally questionable decisions, you uncover a conspiracy where stolen hearts are being used to fuel a sinister underground emotion trade. The game challenges players to choose between self-interest and the greater good as they unravel the heart strings that tie everyone together.
