I liked this game enough to be a Patreon supporter at one point, but the writing was on the wall that the dev was going to burn out pretty fast. His Patreon goals included outcomes for when he had over 1000 simultaneous donors. He just overestimated how easy it would be to become one of the top AVNs out there starting from nothing, and when that success didn't show up, he basically gave up.
Thing is, if he'd launched this same game a few years earlier, he might have been one of the bigger names out there. Now, though, the market is swamped and if you didn't start before 2020 and you aren't drafting on the success of a previous popular game, you have to be great and consistent for a long time to get big now.
