I have to admit, I was a little unsure about the controls at first. But just doing the tutorial, I found them actually pretty good.
I beat the game as Vince earlier today and the control layout didn't bother me at all. My only gripe with controls is that the turning feels very slow most of the time.
Maybe it'd be good to have an option to change controls, for those who might want to change to a more 'traditional' style. But I'd like to keep the default option too, because I found the combination of A/B to turn and the D-Pad for strafing felt quite natural.
