In a world where shadows possess their own consciousness and can detach from their hosts, players take on the role of a witty detective who uncovers the dark secrets behind shadow crimes. Players must navigate through a labyrinthine city full of vibrant characters with their own agendas, using deductive reasoning and charm to gather clues. Players engage in dialogue, solve moral dilemmas, and manage shadow-based puzzles, challenging the societal concept of identity and personal responsibility. Each choice influences the narrative, leading to multiple possible endings based on the player's interactions with both people and their shadow counterparts.
