In 'Whose Shadow is That?', players step into the role of a once-reclusive author who suddenly finds themselves at the center of a bizarre series of shadowy occurrences in their quiet hometown. Strange shapes flit through the alleys, and townsfolk are disappearing one by one, leaving only their unsettling shadows behind. Utilizing clues scattered throughout the story, players must engage with quirky characters, retrace their steps, and unravel the mystery before the shadows claim them too. Each choice influences the storyline, leading to multiple endings based on whether players are clever enough to unmask the shadows or if they are swallowed by their own doubts.
