Don't really know how to react to be honest haha.
I get that people that are only interrested in RHC want exclusive content of it, and don't want to see any other news. Alright I understand that. So you say that it would be better to create a second page.
Let me tell you why I think having 2 pages is not a good option.
Have you think about the people who are interrested in both projects? That would mean they have to subscribe to 2 pages and pay twice the money. Honestly, I wouldn't mind having double the money (hmm...

) but I prefer to thank the people who trust me and trust my work by offering them a single page for all the content I am making. And if you are not into my other projects, well consider it just as a bonus. (take it or ignore it?)
Moreover, as people above said, I am NOT a studio nor a professionnal in any way. I am alone, a single developper, working on it as a hobby. Having two pages would be honestly too bothering. I also have a SubscribeStar page (requested by the persons who can't use Patreon), imagine having to manage 4 pages! That's just not possible.
Also, I am working on both games at the same time (with a focus on one of the game depending on the moment). Already made progress on RHC as my Patreon page says, and also worked on WIAS. So what would it change having 2 differents pages? Instead of making everyone confuse and accuse me of "milking" twice the people who are kind enough to donate money?
Finally, my Patreon page is called Restore Her Career, that's true. I don't want to change it because it would change the URL of the page (which is written in the game itself right now, so I need to think of how I could change without making too much trouble). If you check my page description AND title, it clearly says that I am making 2 games. Also, look at my SubscribeStar page, it says "kalyhagames" because I created it when I knew I was going to make a 2nd project.
Well, I hope you get my point.
