I can answer most of it. Yes its still being made. Yes the Patreon page is down, however there is a different page https://www.patreon.com/Futa_Fantasy/posts (this one) that has more information and has posts made about the progress of the game up until now. The last post was only like a week ago so the game is NOT dead. However, it might be dead on Itch if the creator just didn't wanna update it on Itch, or if they are just waiting for something.
