Step into the shoes of Lina, a witty private investigator who is thrust into the chaotic world of shadow manipulation. Shadows aren't just mere darkness; in this universe, they have minds of their own. As Lina navigates a web of secrets involving a clandestine shadow society, a missing person, and a shadow that has begun to exhibit human-like behavior, players must use their deductive skills to solve puzzles, interrogate quirky characters, and unveil the truth behind the shadows trying to take over. With each choice that affects how shadows perceive you, you'll determine whether the outcome is a rescue, a betrayal, or an all-out shadow rebellion.
