To be honest, I think the Forest could be a good actual separate section of the game, maybe with more places to explore and lore to find that's out of the way of the normal objective there. However, when I say this I want this to be considered after the main story gets developed a bit more.
If this somehow gets added, I think the Guest AI should also become more 'subtle and watchful'. Like if you're wandering around the forest you could occasionally get glimpses of him, and when you least expect it he would attempt to come after you like a slow horror game. Perhaps there could me a direct way of defending yourself outside when you cannot barricade a door, like being able to get some items to throw at him or a flashlight.
