The music in this game is perfect! I don't know if you timed it to crescendo when you activate the last shrine or pass through the wall, but it did for me, and it was chilling!
I did not time it on purpose, but I knew that it took roughly 5 minutes to get through the game if you know what you're doing. So I tried to find a track that was just a little longer, and it just happened to work out thankfully! :3
