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.
Maybe add the vore tag for extra visibility on the project? That is usually how I find these kinds of games. I found this one through one of your comments.
Small, low-effort sprite variations for each individual enemy, so each time you fight another one, they look a tiny bit different.
Instead of adding moderately-difficult enemies who have a few different attack patterns later in the game, like how some platformers do, I think you should make easy enemies with lots of attack pattern variants closer to the start of the game and so on. It's always fun progressing further into the expanse of the map with the promise of finding a new enemy, but adding some unpredictability to the same enemies we face every time spices the game up.
Put a lock on the gallery you haven't already defeated or been defeated by :P
Male/Female Predator/Intercourse Toggle. Like if someone wants AV on, just not for males. Or if they don't want female/female secks scenes in their gameplay. Instead of their grapple, maybe they just hit you?
When you take the defeating blow, a nearby enemy of your preference has their fun with you instead. Or maybe if one of your preferences isn't nearby, they drag you off to them, or instead offscreen. Or maybe they throw you down to one of your preferences? Maybe they tie you up as an implied present for someone? If it's too much work, maybe just break the atmosphere with a toggle for individual enemies.
Some of these ideas look like a lot of extra unnecessary effort, but it would be a big QoL for players. 😭
It's your game, of course. I just hope you enjoy the development process. I understand if it doesn't fit into your vision for the game. I am a big fan of your work.
