Incredibly impressive visual style! And a really neat way to design puzzles using a different sort of mechanic.
Being able to see the sound waves is, obviously, the most amazing part of the experience... to the point that I didn't really pay attention to the murals on the wall the first time through. I went back to give a proper look because I realized they were telling a story, but I'm not super sure what it was. I think that's on me, my understanding is something like a place which was sealed off which people wanted to get into and the big button at the end is how the door opens. Am I close? Did the character with the crown infiltrate the place to let people in or did he kick everyone out at first and then regretted it later? Or am I totally wrong? :D
