Whose Shadow is This, Anyway?

Step into the shoes of Penelope, a quirky amateur detective with a knack for the bizarre. One stormy night, you receive an anonymous letter inviting you to a remote mansion where shadows are not merely reflections of their owners, but living entities with minds of their own. Your task is to unravel the mystery behind the shadows, each of which carries the secrets of their owners. Engage in witty dialogues, unravel intricate puzzles, and forge alliances or rivalries with the eccentric inhabitants of the mansion, all while dodging the looming presence of the shadowy antagonist who seems to know more about you than you do. Can you uncover the truth before your own shadow turns against you?
