Hi!
Yes, that’s a feature I’d like to add, so audio controls are on the GoB roadmap somewhere.
Unfortunately, I’m a complete beginner at coding, so it isn’t near the top of my to-do list! Sorry to hear the audio in the game is interrupting your music of choice. For now you might have to settle for silence or the audio included in the game.
That said, a lot of thought goes toward selecting the tracks / SFX, and I often edit them to better fit the story.
You could try muting the game tab?
That’s what I do when I’m playtesting and have my coding playlist in the background. If that doesn’t work for you, you could try another browser. You could also listen to your music on a different device, like your phone or a tablet.
Otherwise, best of luck in finding a better solution!
