In a world where emotions manifest as sentient artifacts, players take on the role of a 'Heartkeeper' who traverses various heartworlds—unique realms embodying different emotions such as joy, sorrow, anger, and love. Each heartworld is filled with quirky characters and situations that challenge players to confront their own emotional pasts. As the Heartkeeper, you must navigate puzzles and engage in deep conversations to restore balance to the heartworlds and recover the lost hearts. But beware—the darker the emotion, the wilder the character! Will you be able to piece together the hearts and help the inhabitants find closure, or will you find yourself lost in the labyrinth of feelings?
