I really loved the atmosphere of this game! I appreciate that the gameplay was also just walking around the atmosphere lol.
I like the idea of absolutely no "gamey" kind of information that would break the total immersion this has, but this causes some problems too. I initially missed the instructions in the house, but gamer sense told me to pick up the log on the ground after I went exploring. You probably don't want people walking around for 25 minutes trying to figure out what to do, so some positioning of the player to see the instructions could help. An idea might be to have the player start at some safe observational outpost with instructions in the room.
Also, I stopped at 3 firewood and returned before I found the instructions. For game rules that don't make too much sense (requiring an exact amount of logs) some UI might be best (e.g. a "1/4" text). But then again if you force the player to read the instructions beforehand you wouldn't have to.
Great game (:
