Acolyte is Normal apparently while Warrior is Black's Hard difficulty.
It's a great sequel, really. They've revamped combat to be a lot more mobile, enemies are tons unfairer, Ryu both takes and dishes out more damage and all the little touches, like unobliterated enemies suiciding you and Lunarr XXY combo explosive decapitation, make playing the game a massive thrill every time. That said, the bosses are maybe a bit too different: In the prequel, bosses would have really small damage windows for Ryu to exploit, which would effectively have you trying to discover what kind of trick(a well-placed ninpo, wind run+flying swallow at just the right time) would open more of these windows. But in the sequel most bosses have a fairly large damage window, so you can deal damage in a constant stream. It's alright, I guess, fairly realistic in a way, but to balance things out, they've made half their abilities take two-thirds out of your life. It's an interesting balance.
Having said all that, Falcon's Talons->flying swallow+izuna otoshi or vermillion bird strike+hungry wolf=awsometacular!
