Cool concept of balancing combat and movement.
It was a bit frustrating to see an enemy appear too close to be able to respond, since turning is so slow. I would have to [S] then [A] to run away, turn around and shoot, which got fairly repetitive (and not fool proof). If the movement was a bit smoother (faster rotation on [W] or the ability to dodge more effectively, or having [E] and [D] shoot in different directions so you can choose which one to use) that could compensate for the slight clunkiness of it.
