In a whimsical yet eerie kingdom, players take on the role of a quirky heart detective named Aveline, who has the peculiar ability to see people's true emotions as vivid colors. When the King mysteriously falls into a state of existential crisis and gives away his heart to a bewildering array of bizarre characters, it's up to Aveline to navigate through a tapestry of zany personalities—from an overly emotional jester to a heartless witch—each with their own motives. Players will engage in wit-laden dialogues, make choices that influence the outcome of encounters, and solve bizarre puzzles intertwined with deep emotional truths. The story explores identity, love, and what it means to have a heart in a world where feelings are currency. Every decision alters Aveline's perception, shifting her emotions and colors in a playful yet dramatic narrative experience.
