As for the music, I just checked again and I definitely don't have any music. At the same time, elevator sounds and keystrokes are present, and I use firefox, although I doubt it's because of the browser.
Oh dear! I just downloaded the Firefox browser to check, and it turns out the background music doesn't play there either.
I apologize for the inconvenience, but the background music should play properly if you use the Chrome browser instead.
That's why I was really surprised that the game has great visuals and sounds, but no music :D I hope I helped you catch this bug!
