I can totally see how this prototype could be the start of something really amazing! Initially, it gives me "Dear Esther" vibes - and I can imagine how this could be a very cool environmental narrative game. My goal whilst running around and exploring was to get inside of the volcano, and when I did, I could just continue walking on the fire - and there was actually something really fun about that! I think this is an awesome start to something that could end up being really awesome! Well done :)
