Hahaha I’m so glad you enjoyed the game!! I think the audio issue is a game bug, not your system, don’t worry! I’ll get a hotfix in quick!
Also, there is no incentive to get grey pearls because that’s the reward you get when you only partially find the deep truth, called a “Shallow Truth”. It will be left on the bar table instead of the shining pearl if that happens! Since you’ve only ever gotten shining pearls, I guess that means you’re an incredibly good listener hahahaha
Again thanks for playing!!!
