NGL. That is looking like a pretty big goal. I'm not an accountant, but as far as I understand, unless you live in a 3rd world country where $50-200 of patreon money is enough for you to switch to a part time job, or if you're living in your car, I think you've really got your work cut out for you.
Besides this game, do you write at all as a hobby? Are you proud enough of that work to be able to share it?
It's great working with the stuff that you enjoy, but the "painless digestion" and "everyone is consenting" concepts are going to shrink your paying audience considerably. Put some extra effort into ironing those details out in your worldbuilding.
I don't know if you have already, but I think you should compare your stuff with other rpg maker vore creators like Oppi or Schagura. There are other examples of pixel artist vore games or rpg maker developers who have had some monetary success or decent traction. I'll give more examples if you're curious and don't know where to look. Good luck with your project though. I really hope you make it.
