Holy shit that was easily the coolest thing I have played in this game so far. The game feels still a bit clunky especially with the WAY too slow mouse speed and movement, but you completely nailed in the athmosphere and audio department! Also this is by far the most creative use of the theme expansion I've seen!
This really has soo much potential to be something greater if you put the effort in it!
Great Job!!
(Btw the downloaded version for windows didn't render at all on my system. I have a AMD Graphics Card and I heard Godot had some issues with them, so maybe look into that)
