Thanks for the feedback! I'll try to fix those typos as soon as possible!
The faith attribute is meant to be more of a mysterious attribute and something you have to trust in to get a reward out of, kinda like real faith. Since the jam is over, mechanically it does two things, for each point it decreases the amount of health enemies spawn with and gives you a small XP multiplier. It's two things that are hard to notice but have a super big impact on the game if you invest into it.
Thanks for playing! I'm glad you enjoyed it!
