In a world where shadows possess sentience and can manipulate reality, you assume the role of a shadow detective, Sam Shade—who happens to be haunted by an elusive shadow thief. As you delve into a vibrant city filled with quirky, anthropomorphic shadows, you must interrogate shadow suspects, solve riddles, and navigate shadowy labyrinths to reclaim stolen shadows before the upcoming Shadow Festival. Each choice you make alters the environment and reveals the truth behind the ghostly heists, leading to multiple endings that are as unpredictable as shadows themselves.
