>I can't figure out what to do to progress.
You need to escape the forest and get back to the outside world.
In order to do that, you need to get your bunker key back.
You need to find the doctor who stole it and take it back from him.
The way that you find him is up to you, there are several branching paths to finding him and getting your shit back, but the most obvious for new players is the friendly Wolfman telling you to meet up with him in area 2.
If you look at the map it will be split into three regions, each has tougher monsters and night events than the previous one, but will pay higher rewards for surviving.
