Overall, I love the atmosphere of the game; the level design is great, and the art direction is top tier. I think there are some elements they experiment with that don't work. The blood vials, for one, are such a pain in the ass for the first 1/3 of the game, and you end up having to farm between boss attempts, which just feels really bad. Not being able to reset an area at a lantern also feels bad. But the parry system is so satisfying to use, and the weapon design with the special type for each one is very well executed. Though I really enjoyed some of the boss fights, the majority of them were really unfun - they seemed really interested in giant beast bosses that only fit 20-30% of themselves on your screen at a given time, making it harder to dodge and creating all sorts of pain points with the camera. But the good fights are really good.
