Bound to a set of special puzzle-solving rules, he must uncover the hidden mysteries that have been tampered with in every fictional scenario he enters and expose the forces manipulating the plots. As he eliminates false rules, he continually unlocks new permissions, solves one layered cross-world mystery after another, and ultimately breaks free from the space's endless cycle.
