That reminder that the cult is just expendable resources made me love the game. I name them after my family and friends, and after I ran out of names, started adding numbers. So sacrificing Mom 4 and Sister 5 to the Outer Gods, only to save a new cult member and naming them Mom 5 and Sister 6 makes me laugh.
I was surprised to see two games called Knightfall. Not the one you're referring to (assuming it was a typo), is a 2D dungeon crawler, and came out in 2017, with 13 reviews.
Huh, interesting that it's OK to have such a similar name. Maybe it's all OK until someone complains.
