A few people clam its not but it's been over a year without any updates so I'm going to say mostly yes. I still check back on it from time to time because I was really interested in the Dragon guy that was supposed to be next.
last time I looked at the patreon it seemed like he was just doing art and commission work for his patreons. He do talk about it be but as far as I know no real update has been made apparently he's dealing with some IRL stuff that's taken a toll on his mental health. 2020 is hard on a lot of us so I'm saying it's dead for now but may come back later.
