Thanks for putting the game together! The sound issue I had was that the sfx assets (like walking steps, sliding, etc.) wouldn't play at all when I lowered the master volume to about a half. So in order to hear them I had to have volume at max.
This is a fantastic game. Looks and sounds great, and the puzzles are super well designed. Good difficultly curve, well-designed puzzles overall. You guys have a knack for this!
