I think this game would be much better for a select few that don't get parries if it was better explained. I play a lot of fighting games, so I picked up on how it works fairly quickly, but I can see how it can frustrating. If they had said that smashing the stick in the direction of the attack and hitting weak attack parried, It would maybe make more sense. Having to go back to neutral to start a parry can be a little confusing to people when not properly explained.
Couple a proper parry tutorial with blade wolf being a trial by fire would be a perfect lesson to drill it into people's heads.
That said, once you "get" it, the game on Normal becomes insanely easy, as you can start parrying attacks from all sides and Zandatsu multiple people at a time. Not that I mind. It's fucking badass.
On normal, I probably took only one or two hits from Sam, and just parried the shit out of him the rest of the time. I can't wait to finish the game and try again on a harder difficulty.
