This looks incredible, and even quite revolutionary. (I myself didn't even dream of something like this ever happening.)

I wish you good luck in expanding the possibilities, and keep up the great work!

This being on top of JJ2+ instead of being a conflicting add-on is also a great plus (haha c wut i did thar)

This would be SO useful for my city, even to the point of getting my enthusiasm back on track. The music change and camera control featured look VERY tasty.

Again, great job.

EDIT: I have run a few tests, seeing as there previously was no way to change the max health in single player (I think so at least), so I attempted to save with around 20 hearts. I was surprised that everything was okay, including the external script. So far, it looks stable.
