All this control talk has me scared. I like shooters, I have like 5 equipment keys, 3 movement and an interact.
I've always hated games that are like 30 moves, all of which are like do low low high low parry high for super omega attack. Great pull some of them off slowly in training or something but then if the games at all difficult and heat of the moment i'm usually following back to a few simple moves.
The flow though sounds like cant be as simple as cheating with one of those crazy mice with 15 sidebuttons.
