Just finished Guardian Ape, and up to this point the only fight that I was completely frustrated by was the Lone Shadow Swordsman, and that was mainly because the camera there was atrocious.
The game doesn't seem as ball-bustingly difficult as it was made out to be. It's easy enough to just mash the deflect button for most enemy combos, at least to this point.
Maybe it's because I've only played Bloodborne before this, so I don't have a lot to unlearn from the other games.
I'm far from high end, I just know what suits me.
