In this interactive text-based game, players take on the role of a reclusive author who awakens one morning to find an assortment of bizarre and disconcerting letters on their doorstep. Each letter features a different, anonymous sender with seemingly mundane greetings, but as the player delves deeper, these hellos unravel layers of strange connections to the author's past and a series of unsettling events. As they respond to each letter, the narrative branches out, revealing hidden motives, complex characters, and the chilling truth about who’s been observing their life. Choices matter as players must navigate trust, paranoia, and existential dread, leading to multiple possible endings.
