Oh man, I really had tons of ideas for that! I wanted to have it so you could position the holy candles yourself and lure the monsters into your traps. I even wanted to make it so you could give the monsters food/blood to direct them away from areas you need to access. In fact, the book at the end was supposed to be a spellbook that you could regularly use to get powerful protections or advantages.
And the lore was going to be pretty dang dark. Stuff like abandonment and abuse along with traditions that were taken too far.
Ahhh... time makes fools of us all, though. <:3
