1. No to discord, however you can use the game's comments.
2. Always been a game dev, had cool ideas, wanted to make them exist
3. Cool idea! I just don't know much about any exhibitionists and try to make the game convincing in terms of "why would he / she do act a or b" - so it won't have the classic stereotypical "port plot" or porn-brain and instead something more from the day to day. Not to say exhibitionism is, I just don't know enough of how such a person thinks / moved to do it good (yet). I like the second idea, and also already know that game!
Thank you for the kind words / suggestions, feel free to share more of your thoughts!
