LOL, I downloaded it a couple months ago and got lost, hit escape, and never looked back as the contest was on my mind. I crawled back into it yesterday and got lost again then opened the mesh in another program. Very clever! What I didn't notice upon entering the cave was the immediate drop, which had me running in circles, likely passing the entrance endlessly! (Even yesterday, when I saw the entrance, I still couldn't climb out!) Nice!
