WASD movement is pretty standard, the camera movement on the mouse seems... fiddly, I mean it would adjust the camera whenever I move the mouse a little.
I've expected WASD (AD = strafing) and mouse left/right = pivoting. up/down tilting. Camera pivoting would be a combo of button+mouse left/right.
I don't know, playtesting might prove it to be an excellent system. Tho Its standardly been done differently for a solid reason I guess.
