Hey, and thank you for playing!
Currently, there are three paths to take in the demo: Alone, Alexander, and Koumo.
Two other paths are being worked on right now: Petronilla and Elis. The grayed-out options are connected to their routes and are unavailable until then.
To get on Alexander's path: At the bar - seek help from a stranger.
To get on Koumo's path: At the bar - walk away, and then follow the hooded figure at the market.
You are only able to read chapter 1 in the demo. It ends after you get in the car with the guard, no matter which path you are on.
