Well, I am not really doing anything special. Without entering in the whole idea of the game, there're some NPCs around the corners that gives you clues so you can get out. The things is that the map is changing so you can't take their clues as true unless some requeriments are met. There's not really a (conditional) dialogue, it's only them. I'm also open to improve the game itself, if you had any idea in the way.
