Small patch, but the old rock sound was grating on me and I noticed it from the feedback players have been leaving too.
You can also mouse over keywords in the data book. (You can view the book in the middle of a run by clicking the options menu in top left -> "View Book")
I will keep brainstorming on how to make concepts clearer and also improving other feedback from players. Thank you!
