I encountered a bug, a visual one, and not that affects the gameplay though. The pool at Ms. Knives' doesn't have any floating candles, when it's clearly saying that there is one on the dialogue.
I tried it and based on my observations, it made the Primal, attack a bit earlier. And I think it's just the same distance covered by walking.
Note: This is not confirmed and I don't trust myself. Maybe you could try it?
Instead of giving you the answer, imma give you a hint, GO NORTH.
Found 5 endings before the true ending, love the game...
