Dude, relax. No where does he state he won't update on Itch. The chapter 5 release on Patreon is still pre alpha. It's an incomplete version of the chapter. It's not 100% completed yet. The dev even addresses that here if you care to look. You can see the completion status of Chapter 5 over on the Patreon page as well. Still a scene and a half needing to be done for Chapter 5 to be considered complete. 

its not the dev downvoting you, it's other players who actually read. Patreon subs always come first in these games, then itch, nobody stole anything from you. you are getting exactly what you paid for; you don't get to complain that you didnt recieve an unfinished update before it was finished.
