In a world where interstellar travel is commonplace, players take on the role of a quirky cardiologist aboard a spaceship known as the 'Biodiversity Ark'. The Ark is on a mission to collect and preserve the hearts of endangered species across the galaxy, each with their own unique emotions and backstories. However, an unexpected event takes place: a malfunction in the ship's life support system causes the hearts to start swapping places with the crew, turning the ship’s inhabitants into dramatized versions of their collected emotions. Players must navigate the ensuing chaos by engaging in conversations with crew members whose hearts have been swapped, uncovering deep-seated fears, desires, and hilarious misunderstandings, while trying to restore order to the ship before it reaches its destination. Choices impact not just the fate of the crew but the restoration of the hearts—can you figure out whose heart is whose before time runs out?
