This will probably reveal my incompetence with coding (because hopefully, this doable/easy), but can I insert some sort of a feedback mechanism within the game itself (i.e. before the reader reaches an ending)?
I am thinking, maybe at the end of each chapter (and within the page text itself), there can be the following: "Rate this chapter: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10"... where each number is clickable and shoots me a pre-fab message once clicked ("such and such chapter received a such and such rating").
Or maybe: A "Give the author feedback on this chapter." button where a window pops up and the reader can destroy my life's work at their leisure, but then is returned to the game once they hit send?
