Yeah, the wolves irritate me, I've just been rolling and attacking my way thru so far but despite their large physical size I feel like their hit boxes are a lot smaller or something, I miss them more often.
With the slow trial I just turned the camera and stopped between streams, there was a large enough gap to be able to stand and not get hit. What I didn't like about that section was the inconsistent rules, not the 'game' rules each room sets, but like some times I could stand on top of the boxes that shoot, and they'd keep shooting, sometimes that'd cause them to blow up and hurt me. Very strange.
As you said, it's a little rough, but I'm pretty blown away so far. The only bit I think actively sucked was searching for the kids who improve weapons' mom. I hope I never have to go back there, and I'm pretty sure I will have to.
EDIT:
I was wondering how far in I am, I'm on 13 hours and I'm about to get my first boat ride? I thought I was about half way, but I think there are only two more story based trophies left to get. Also, I was looking at the trophy list, and I think I got a big spoiler which sucks ass.
