I liked the sound of ambience that you added. Things like that are easy to forget and don't seem to do much, but they really immerse the player and make the setting feel a little more real. I really liked hearing the sound of the wind rustling, it felt colder and crisper. I do think a win condition or other goal would complete this game pretty well, as I quickly realized I didn't have to do anything about the campfire and could just let it die while I kept making torches to keep myself warm as I travelled warmer. Great job with the presentation, and it could definitely add a few mechanics.
