If you're curious about the hacks I made:
Added a harm counter system that counts up when morale reaches zero. We wanted something with more serious consequences, since it's a thriller/horror game.
Lowered the XP bar requirement (renamed it to Savvy for flavor), because this specific game is a one-shot, and I wanted to ensure people could get their level ups at least once.
Replaced connections from backgrounds, with a story specific mechanic called "Masks" which essentially gives each player unique powers or abilities.
