GameSpot regarding the controls:-
"While the mechanics remain the same whether you're using the Kinect or a standard controller, the experience is quite different. The default standard control scheme has you holding the A button to lock on, the X or right trigger button for rapid-fire, and the B button to activate euphoria. On the Kinect, you wave your right hand to lock on to enemies and then flick your hand forward to release the shot; you use your left hand for rapid-fire and put both hands in the air to activate euphoria. There's also an alternative control scheme where you clap your hands to change weapons. Either way, you're only required to move your hands rather than your entire body when using the Kinect"
"Both control schemes work well, but the standard controller is easier to use. The Kinect tracking is good and the camera sensitivity can be adjusted in the menu system, but there are times when weapon changes will unintentionally move the camera and leave you feeling disorientated. But what the Kinect loses in ease, it makes up for by being the more immersive experience. Aside from allowing you the freedom to move in time to the music, it gives you the feeling of conducting an electronic orchestra as your movements directly affect the music and sound effects. With either control scheme, you can elect to put standard controllers in your pockets and have them vibrate in time to the music, which complements the rhythmic shooting."
They ended up giving it a 8.5 out of 10.
