A very cool mod. I've always wanted to put it in the game. By the way, I had a cool idea. You recently posted an update with the mechanics of music. I recommend in the configuration settings to put 4 themes to the taste of the players. I have given examples in the text below. There will be links to the topics so that you understand what template to do:
Bury the light(Vergil's theme):https://youtu.be/az3qwXf4Z-I
Subhuman(Dante's theme):https://youtu.be/W9pkxmKrQWE
Devil trigger(Nero's theme): https://youtu.be/KhRYLxRzgqY
Crimson cloud(V's theme):https://youtu.be/x5Mmb4ZBZIk
