I'm like 30 minutes in, but the deflect mechanics feel straight out of Metal Gear Rising or DMC's Royal Guard. I'm still learning all the enemy attack animations through trial and error, but it's really not bad. I think this game is far more fair than Souls games, because I never feel like I'm underleveled, and I vastly prefer this kind of game design.
Fucking A++++++++++++++
Also, I found my favorite control scheme:
Attack on triangle, Deflect on circle, Jump on X, and Action/Loot is square
Hold R2 for easy Run control with thumb still free to do a running attack, and easy access to mid-battle Step Dodge
Grappling hook feels best as a shoulder button, so I put it on R1.
Prosthetics are all controlled via L1/L2.
I switched D-Pad up and down because of personal preference.
The only thing I'm toying with is switching the face buttons so that Attack is square and Deflect on triangle, making Action/Loot as circle. I think I like this set-up the best, though.
