First of all, sorry is this has already been answered/stated and I haven't seen it. My bad! Sorry for the inconvenience.
In any other case:
I've played this game, and I honestly love it, but, of course, it is indeed a short game. Not saying that it's incomplete, it's just like I felt that I needed more of this masterpiece.
Anyway, I had some trouble with the gallery and viewing the +18 content in it ( ͡° ͜ʖ ͡°), so I dove deep in the game's files and (kind of-not entirely) fixed it by myself. Then, I kept looking in the files, because I love to do that, and wondered if I could mod the story in any way. I have moded some games previously in Ren'py (unfortunately, none of them have been finished *sad noises*), so I was wondering if I could mod this game aswell. I have no intention of selling the mod, nor to distribute the entire game for free. I'll just share the rpa file(s) of the mod wherever I can (I'm not close to being famous, but I'll try), state that is fan-made content, and, of course, meant to be played after having read the original story, not instead.
This wouldn't be my full-time activity, I just wanna invest in this game some of my sparse free time. Nevertheless, I understand if the permission is denied (it wouldn't be the first time, hehe).
Have a nice day, and thank you so much for stopping by!
