In a world where human emotions are tangible strings connecting each person, you play as Alex, a person who wakes up to find their heart—literally!—missing. With snippets of memories and heartstrings left behind, you embark on a journey through various emotional landscapes that represent different feelings like love, grief, joy, and anger. Each landscape is a unique zone filled with characters shaped by these emotions, and your task is to navigate through interactive narratives, solve emotional puzzles, and help others confront their feelings to piece together where your heart has been taken. As you explore, your heartstrings pulse with each decision, influencing the outcome of the game and how you interact with others.
