I was unable to get the pointer to work (I don't have a wiimote so I couldn't try that part as well), but just riding on the back of the dragon was fun. I have an excercise ball and I was able to try bouncing on that while riding it. That was a trip! It was strange to be on the edge of sim sickness one second because of vestibular disconnect, and then start bouncing and feel totally fine (it even felt like I was experiencing higher g-forces on the bounce up, and that fit with this feeling that I was accelerating upward very quickly).
Unfortunately it seems like the 3D scenery runs out about half way into the song. I would really have liked more to look at.
The dragon model was cool. I'm glad I tried this out.
