It has been a long time since I looked at this, but IIRC I set it up so that you can pass whatever data you want between scenes. So you should be able to easy modify it to pass whatever you want between levels - I probably just had a helper that managed some things automatically as a common use case.
I think I made some upgrades to this in my game template (which I also haven't looked at in a while). Maybe that will be better suited for your needs?
