Did it start that way or break after a certain point? Did you send your own directory to your friend’s computer (sharing is encouraged, just trying to diagnose.)? It could be something in your player prefs.
It didn't start that way on my friends computer, but we were having a problem with the backing track playing on the dome level, so we reinstalled and that's when it started. Then later I downloaded the game off itch.io from the Bundle for racial justice and the problem happened for me straight away.
