Cool game! I thought the campfire mechanic was cool as well as the signs showing the controls.
I thought the game could have introduced a tutorial; even though I read through the controls it was still a little hard to grasp the game. I couldn't find any survivors either, but I did find wolves.
I also had trouble figuring out what my warmth was. In my attempts to find out where the survivors were I often froze to death.
Overall though I enjoyed it! The pixel art was charming and it was cool to interact with the campfire. Great submission! :)
