I very much enjoy the "mood" you've set with this game... it's lonely, but somehow the music still makes me feel a little hopeful. I was enjoying the mechanics, found a lovely glowing tree... but then I got stuck under one of the lower passages. So I tried again, avoiding the place I got stuck the first time, only to get stuck under another low passage. It seems maybe the collision box on my character is getting caught somehow. I couldn't crouch or walk in any direction once I got hung up.
