This is absolutely incredible. I can't begin to describe how cool this is and how surprised I was to see it, but at the same time realizing this might be why you started making a game to begin with.
One thing I would very much like to see is the possibility to EXPORT and IMPORT your settings or any other means of sharing with a friend to test out and give feedback.
Would also be useful in educational settings as well. Being able to turn it in for an assignment.
