Bro, every single HTML/Twine game has the code right there. It's HTML, just edit the file in notepad. Fuck, you can even edit it with the browser's dev mode (F12) while playing. For this game, I usually add a 12 hour nap button to skip the day. You can do more than 12, but the game gets kinda fucky if you don't manually sleep so the "sleep" passage can do its thing to set up the next day. And I usually boost the perversion gains by around 2x (by just editing the file with search/replace) so there's less grinding.
