Ah, I sort of forgot about the slowly reducing max health. I think that and the different parry timing (the best mechanic in all the games, baby baby) made me quit it the first time I played. I don't even remember it bothering me in the second time I tried, maybe because I had played elden ring and dark souls again at that point and didn't try to horde items.

Pre-edit edit: Wait, I remember now. I played the game the way it was 'meant' to be played, with a giant weapon and just beating everything up before they could get me. I remember telling my friend that the openings in the boss attacks felt like they were specifically designed around the giant weapon timings. It just made everything easier.
