I feel a bit harsh on this review because overall everything was well made and obviously with more time more stuff could be added. This was my first review and I was not quite in the mindset but after some thought I have a few suggestions which I feel is a more appropriate way to respond!
Maybe a threat is in the dark? Or maybe if you are in the dark for too long you lose? Then you could make it so that the light of the fire slowly dwindles while not fed.
Leveling up the fire was very cool!!
