In a city where shadows have a life of their own, you play as Sam, a detective specializing in 'shadow crimes'—mischaps caused by rogue shadows. The game unfolds through your exploration of various urban settings, where you interact with eccentric characters, solve problems dictated by shadow behaviors, and unveil a deep conspiracy surrounding a mysterious shadow that appears in every crime scene. The choices you make affect not only the outcome of your investigation but also how shadows respond to you, leading to different endings based on your decisions and the alliances you forge.
