In a city ruled by shadows, players step into the shoes of Mortimer, a washed-up private eye with an unusual twist—he can communicate with the shadows of people and objects that have left behind their leftover energy. Tasked with solving outrageous cases ranging from the disappearance of a local poet's muse to the theft of the infamous 'Shadow Diamond,' Mortimer must navigate a maze of quirky characters and mind-bending puzzles while uncovering the deeper story of a shadowy conspiracy that threatens to engulf the city. Every choice influences the shadows' reactions and reveals the city’s hidden past in unexpected ways.
