I haven't played this, so I can't fully judge this, but it I was really turned off at this:
I thought about syncing it to a default music brick of custom midi sequencer sounds, but you wouldn't be able to move fast enough, and the way the notes are played randomly I would have to create each song, which is more work than I'm willing to put into this little project.
I did show you guys how to edit it, you could try what I said above and post the bl save here.
