Youdunnit is a solo journaling RPG. It is a game about deception and the claustrophobic dread of guilt and fear. It is a murder mystery in which you are the murderer. Youdunnit was created as part of the Wretched & Alone jam, using the Wretched & Alone SRD, and is inspired by the likes of Agatha Christie's Poirot and Rian Johnson's Knives Out.
