In 'Whose Heart Is It, Anyway?', players step into the shoes of Echo, a cynical heart-thief with a penchant for mischief in a world where emotions are tangible entities. After a botched heist in the city of Feelingsville, Echo accidentally fuses their heart with an eccentric assortment of stolen emotional fragments - happiness, anger, joy, and despair. Players must navigate through whimsical yet dangerous realms, solving puzzles based on emotions and engaging in dramatic showdowns with personified feelings to reclaim their own heart. Will they risk it all to piece together their fragmented soul, or will they embrace chaos and the thrill of feeling everything at once?
