Yeah, KD rules on PS2. The controls are pretty easy:
Both analog sticks up - moves ball forward (away from camera)
Left analog up, right analog down - turn right
Right analog up, left analog down - turn left
Both analog stick back - moves ball back (towards camera)
You could emulate these basic controls pretty easily with the touch screen. There are other controls (if I remember correctly, pushing down both analog sticks turns you 180 degrees) but this is about as complicated as KD gets. It's an awesome game, I can't wait to see the DS version.
