Really glad you enjoyed the music! I completely understand that the theme isn't strong, even if I had more time to do all the mechanics I wanted. But the idea of how the theme makes sense is, when you change costume you die and become a skeleton, then a ghost and can ask questions to people who will give better answers. Not particularly great but it's the idea lol.
Still, your comment made me really happy, I'm glad you enjoyed the game overall :D
