Its especially the case with lack of content (which obvs its because the game is in early development), it makes no sense at the current time to have patreon exclusive version and public version. Since there is no difference, except just the bugs have been fixed. Obviously as developer you have the say in the builds and what people get, but personally I don't believe that many people would want to support such a game. Happened with isekai awakening + any nergal developed games. They both had big fan base, people realised dev milking/being heavy on the patreon only getting good stuff, people stopped and they lost a lot of income.
