Assuming you mean like the beginning of the video, when he’s going in circles, and not later on when he’s doing the twin-stick style movement: Just move them by their forward transform and change their rotation as appropriate (button is down).
Actually, its best if you use a Rigidbody and change the velocity. If you manually change the position, it can ignore collisions and go right through walls. With a rigidbody, however, if it hits something it will stop or bump if you have a physics material on it.
