Simple gameplay, but effective atmosphere. You did a good job with the art and atmosphere. It helped that everything was maximally cohesive, it all just clicked and made sense together.
The play space was large, but I feel like that added to the bewildering nature and the game definitely seemed to mess with your perception and placement within the space (I distinctly remember changing location once in a seamless and head-scratching way. My one note would be that a little outro piece of music would have been nice for the ending. The endless ambience had kind of run its course by that point. Small nitpick, though. Very quality stuff.
Great entry!
