I doubt you're interested in my response, but I'd like to answer this. First of all, I wanna say I get what you're talking about, and I completely understand your feeling.
However. Extra content in FFM is extra content. It's not like I rip anything off the base game and put it under the paywall. Those scenes are additional, a nice bonus for my supporters. My game is whole as is. Patreon bonuses are bonuses.
Also. If you believe that my game or any other Twine project is just clips taken from porn, I advise you to visit all the variety of porn sites that are on the internet, preferably the "GIFs" or "Clips" sections. I'm sure you'll find millions of porn games there.
Jokes aside, lemme put it like this: if you take away all the porn clips from FFM, it'd still be a wonderful game I'm proud of; if you take all the UX/UI work, the graphical design, the minigames, the procedural generation, the events, the characters, the code, the text, the whole thing.. and only leave porn clips -- that would be a bunch of porn clips.
