Really awesome work! The atmosphere, sound design, graphics and puzzles all worked incredibly well. It was a bit unintuitive at times, and I got suck after the big pyramid shut its doors. Maybe I should have gone inside faster? Also I get the intended effect of making the turning feel sluggish, but it just felt painful to look around.
All in all a super impressive submision!
Edit: Read the other comment and followed the black cubes to the actual ending, which I admit made me jump a bit!
