I've been working on a private variant of this game for years, and have already decrypted and familiarized myself with the file structure, coding, and dialogue. I am a writer by hobby and could very easily solve MITY's problem on a creative hiatus, I'd even do it for free. My issue is I am no artist, and can't render the beautiful artwork his team can produce to go WITH the writing.
I even went as far as to use Project Soundwave to rip hundreds of lines from Azula's actual voice clips from the series and splice it into some very naughty, raunchy dialogue (Sorry, Grey.) However, I doubt MITY even cares to do anything further with this project. And he doesn't exactly leave a public email address to contact him at anyway.
I have made a separate story arc so far that's centralized around Azula with borrowed artwork and voiced dialogue. My main gripe about Renpy is how temperamental and specific it is. It's actually quite tedious, and a lot of work. And I'll admit, I enjoy my private time with Azula so much I'm not sure I want to share her.
