What I've learned so far: it helps to not try fighting the tutorial boss with a hilt. That was not as hard as I was making it. :)
I've also learned that I'm pretty terrible at trying to guess what PS3 controller icons correspond to on k/m.
And I'm kind of put off by the camera. The biggest challenge for me so far is just moving and directing my attacks non-spasmodically. The decisions I want to make are an arm's length from my ability to execute them, so I'm always playing catch up. I'm not used to games like this at all.
