Very nice, dark atmosphere! I didn't have any idea what I was doing though, just running from one place to another, picking up random stuff. Didn't encounter any enemies either. I'm guessing the bark, bones, logs etc. are going to be used in crafting in the bigger version? The stamina system seems weird - at first I never ran out of it, then I'd lose it with just a few seconds of running and only recovered a little bit.
One thing I'd recommend working on is teaching the mechanics, because the player is bound to forget a lot of stuff when they're given a huge info dump at the beginning (I only remembered there was a "rest" button after I quit the game and started writing this feedback). The game does have a pretty solid foundation though, and you clearly have a lot of ambition. Good luck with further development
