This is exactly the same as the one you will expect in AT, just plug in a joystick and enjoy, it should give you some good and effective practice sessions. Keep practicing until you can basically play it without the need of concentration (play it with just an eye corner glimpse every now and then), then try increase your workload by doing other activities like maths or listening while playing this game.
However I had a try of the game with just a keyboard, and my cross kept shooting away from the centre but still! i got 9.29/10, so expect the rating system in KA will be very harsh comparing to this.
