This was great. Reminded me of old-school adventure games with impossible puzzles and no hint books. Very challenging. I got a couple puzzles, but I was stuck on the statue and didn't know what to do with the hourglass. I'll come back to this again, because the art, the music, and the overall feel was really cool. Nice work!
Oh, the controls got me stuck a couple times, with the mouse not quite rotating back to the way I wanted to face, but that wasn't game-breaking.
