5GB .rar file, and you created all this in the jam? Wow! Nice job getting a animated 3D human to work! Beautiful mountains!
It's a very complex game, and hard to figure out how it worked. I didn't finish even on the easiest setting (setting all skills to the lowest setting - which I think should be default in a jam). From what I could read, it was about using abilities to kill the human. But I never saw any abilities, and the ingame time was ticking up incredibly slowly, so I thought it would be too hard. There was a skill tree that I never got any points for, and it was really hard moving the camera and I lost track of the human very easily. I tried both the desert and the snowy level.
It took 3 tries to get the game downloaded, which took more time than I played your game (excluding extracting it!) - I'd strongly recommend trying to compress it way more (and use a zip file instead) next time.
