Fun concept.
Just lurking around the same boring terrains, nothing happening has too high probability I think. Maybe if player could speed up or skip the walking part, it would be nice. It is also not clear why sometimes objects (like gray blocks) appear in the forest and after making the decision it just disappears. It also makes no sense ignoring rabbits, you always gain food if you hunt them. Thirst and hunger meter is good but maybe a health meter would be handy. Or the other way around, hunger and thirst could be expressed in phrases like "you are REALLY hungry" instead of a bar. Sometimes I did not know why exactly the character feels sick with a hanging head.
Glitch: climbing a cliff with a lost leg animated as if the character would have two legs again while climbing.
What is the goal of this game? Walking as far as you can or getting to the king's grave? It was a bad feeling that I cannot continue just because I have found a grave. So what? What if I want more adventure or more kilometers?
Walking together with another character would be a great sequel. Different terrains having different background music would also boost it up.
