Please add a walking animation.
I'm using an XBOX 360 controller and with the slightest tilt of the analog stick my character goes into a full blown run.
I think the animation should be changed so that your character starts to jog or walk a little before moving at full speed. It would be more smooth to look at and control.
EDIT: Actually, the problem might be that one press of the movement button (whether it be on the XBOX controller or WASD) sends you too far, causing inaccurate movement
