In 'Whose Shadow Is That?', players are thrust into a surreal city where every character has a secret, and nothing is as it seems. The protagonist, a shadow investigator with the uncanny ability to see people's shadows independent of their owners, must navigate a labyrinth of intrigue and paranoia. Shadows behave strangely, mimicking, morphing, or even whispering secrets about their owners. As players uncover clues, they must piece together stories of betrayal, greed, and lost love, while also unraveling their own mysterious past and the shadow that follows them everywhere. Unique narrative branches lead to multiple endings depending on the choices made, making each playthrough an unpredictable psychological experience.
