Hi everyone! I was trying to upload a version of my game with more than one audio file, but I'm encountering some issues. I added the Bitsy muse hack, and it works fine when I include just one song. However, when I try to add at least two songs as background music, I receive this error message from itch.io:

Any one knows what could be happening and if there's a solution?

Thanks in advance!

Nico.
