In a city cloaked in perpetual twilight, players assume the role of a street-smart detective named Harper Cole. Harper discovers a mysterious case involving missing citizens whose shadows have been mysteriously exorcised, leaving them in an eerie state of shadowlessness. As they delve deeper, they encounter a shadowy underworld where shadows have minds of their own. Players must navigate conversations, make tough decisions, and solve puzzles to reclaim the missing shadows while evading shadow marauders and uncovering the sinister forces behind the disappearances. With every choice, Harper’s own shadow seems to develop a personality, sometimes aiding in the investigation and other times leading them astray.
