Nice job at using exploration to tell a story. I loved how they're were so many paths and they honestly were intimidating (in a good way).
I liked the choice in choosing my path and also the little text boxes describing how the character was concerned about heat for example really helped shape my choices to be more informed on what path was the one I wanted to take.
The only suggestion that I have is that I would have liked a chickening out ending if you decide to leave the cave before getting an ending, maybe even changing if grabbed something valuable first.
