Yes, the controller can be used to rotate and change it's axis.

I'm not entirely sure what the missing prefab was, but looking at the scene everything that's supposed to be there is. It could be an error brought on by upgrading to Unity 5.3. Either way I'll remove it in the next commit, since the scene works as is.
