It seems that you are content with 200$ patreon money, is this a hobby for you? I would reconsider everything after seeing this huge interest towards the only woman who isn't a love interest or just abandon the project. Not worth it for 200$. I welcome your enthusiasm but it doesn't make much sense for me as a business graduate.
It's a hobby/passion project first. I've wanted to write stories since I was a teenager when I first started reading manga and comics. Visual novels are a great medium for storytelling so I decided to go with it but I was wary enough to know that if I made a non-avn, no one would click on it let alone read it.
With the allure of sex, at least the people looking for plot driven avns would go through it.
As for patreon, I'm grateful for all the donations as it helps fund with purchasing assets and will help in upgrading my system for better quality down the road but it's not my priority. If I was really after subscriptions you'd see a completely different and even degenerate game with predatory transactions/reward tiers.
My first priority is improving overall quality. It's the main reason I invite criticism because it genuinely helps with providing clarity. A lot of people didn't like Savannah's character at first and I couldn't pinpoint why exactly but when I saw the positive reception for Eliza, it helped me realise the changes that needed to be made and which direction to go for future of the project.
