In a world where emotions have physical forms, players take on the role of a heartkeeper—individuals responsible for managing the hearts of others. Each heart embodies a unique emotional state and is tied to its owner's fate. Players navigate a bustling metropolis where they must forge alliances, confront emotional dilemmas, and traverse the tangled relationships of people whose hearts they have in their care. As a heartkeeper, you will face morally ambiguous choices: do you help someone regain their lost heart at the potential cost of another's emotional stability? Collect hidden secrets, uncover dark conspiracies, and experience thrilling encounters as you manipulate the emotional fabric of the city. The game’s outcome dramatically shifts based on your decisions and the hearts you choose to protect or sacrifice.
