Here's my take, $20 per month isn't a big deal to me. I've supported many patreon/SS projects over the years. I might even be considered a "whale". However, the projects I support has to be worth it. And from what I've seen with this dev, is that it's not worth it.
A couple of issues:
1. Very inconsistent. Updates are sporatic. I expect at least one update per month no matter how small. However, I'm willing to overlook this if normal updates are generally content rich, which they are not at the moment.
2. Attention spread too thin. This dev has 5-6 projects at a time(with 2-3 that are completely abandoned) and is actively seeking to increase the active projects count. No. Just make one game and focus 100% on it. You're trying to cast too wide of a net. But you would be far more successful focused on a single niche and creating a loyal fan base.
3. Essentially fraud. I have seen other devs pull this trap before. For example, the dev team for Amnity Park and Breeding Farm. The dev mainly only wants to focus on Amnity Park and develops Breeding Farm on the side. However, Breeding Farm is(was before all the drama) many times more popular but the fans caught on quick on how the dev was using Breeding Farm revenue to fund Amnity Park development. As a result, Breeding Farm was left undeveloped for two whole years, iykyk. The same thing is happening here. This dev loves to make UFO but the fans only care about Incest. And because the dev is developing multiple projects, even if you only like this game, it could go for years with little development while the other game, that you have zero interest in, gets 40+ updates in the same time. You can't help but notice that this game was only created to capture and milk incest fans.
4. Troll content. Everyone loves a good joke. However, that is not the case here. This dev lures you in with decently attractive renders and curvy milfs. You go in expecting to smash these sexy milfs. But then the dev suddenly, for no reason at all, turns them into futas and they penetrate the male mc. That's definitely not what we signed up for. If this is your main content, be open about it. With the TRANSformation tag in this game, I can almost guarantee the same thing will happen in this game. Normal people beware.
5. I don't mind a paywall. Things that are worth paying for, should be paid for. However, there's basically no content in this game anyways. At best 15 minutes of content and a minor sex scene(that has been paywalled anyways). The content isn't so amazing that it is worth my monthly $20. Plus, I have no interest in paying $20 to fund his gay futa game.
