Hi,
The game has a nice atmosphere, it's both weird (in a good way) and beautiful.
I did not understand how to exit the labyrinth at all, I ended up dying a few times (the death sound scared the hell out of me) or just not being fast enough, and the night part is completely black which makes the game unplayable. I had a warning before launching the game about my graphic's card driver so maybe this is a rendering issue (I've read your comment saying that you were not familiar with UE rendering).
Very interesting entry, and congrats on making it!
