I just recently saw a very interesting case: it's about the game

. That game isn't that popular here, it has less comments than this one, for example. Still, he already has 1886 patrons, a similar number than L&P, with a game released just 2 years ago. How the dev did it? Well, he did a very unusual thing: almost every dev launches his game here for free in hope to get patrons, he did the same thing but not only here, he did that in

and it happens that the players there are more willing, by far, to support the dev in patreon than in this site. He released the game for free in Steam since almost the beginning of the project and he updated it for free until v0.03, the game is already in v0.08, so, the Steam players who want to keep playing the game after v0.03, become patrons, because many of them don't know this kind of sites or are not interested in be pirates.
Then, it seems that MarcialART has changed the rules of the game: it's better launching your game for free in Steam and promoting it there than here. Besides of getting a lot more patronage there, you don't have to deal with the constant complaints of people that don't even pay to play it. In Steam each player write one review, if they want, and that's all. Innocence or Money has 340 reviews there, the vast majority favorable. Also, it's possible being popular in Steam and not that popular here, which means that the probability of someone leaking an update here early is less.
To put you into perspective, MarcialART earned almost 300 patrons just the first month after releasing his first free version of the game in Steam, that's almost the double of what you got in all these months. Was he lucky? Did the Steam's algorithm favor him to get more presence in the platform? I don't know. But, my advise is to launch the next update of Ms. Denvers in Steam for free (the landlady one) and ask your fans to download it and write positive reviews since the first day of the release there, that's very important to get more presence in the platform. Then, release a few more free versions in Steam, maybe until v0.08 or v0.10. After that, you keep releasing the game in patreon only. When you have a good amount of content (7000-8000 renders) and there's at least a significant sex scene in the game, then you can release the first season of Ms. Denvers in Steam, now with a modic price. Translating your game in several languages helps a lot in Steam, you should do that for the first season of the game, at least.
