Set in a fantastical realm where shadows have minds of their own, players take on the role of a shadow detective tasked with solving enigmatic crimes that occur when the balance between light and darkness is disrupted. Using clever dialogue choices and observational skills, players will navigate through a variety of quirky environments, interrogate shadowy suspects, and uncover secrets while contending with their very own shadow that may have its own agenda. The player's decisions shape not only the outcome of the investigation but also the evolving relationship with their own shadow, leading to multiple possible endings.
