So on a chinese forum wolfzq complained about piracy and threatened to stop development of the game.
Let me say this first, it looks to me that right now you care more about the money than your fanbase (given your patreon pricing policies). People who currently support you on patreon are most likely not there just for the game, your slow drip incremental monthly updates are so minor that it is (again in my opinion) not worth being subscribed just for access. Those who want the full game will just wait for it to finish and buy it on steam.
People who support you on patreon are people who actually do care about your work and are genuine fans and will be supporting you despite there being a pirated version. People who never intended to pay for the game never would have done it in the first place, if the pirated version didn't exist they would just move on to the next game. We live in an age of entertainment and your work is just a drop of water in the sea. By no mean it is a league above others.
I would argue of the opposite actually. having a pirated version actually works as an advertisement, it lets more people see your work, and those interested might actually really like what they are seeing and decide to support you.
I know you might say you have a trial version out there, however lets be honest, pirates will spread awareness of your work way faster than traditional means (itchio) after all thats how piracy works. Among those who see it (whom many would probably never have known of it by other means) there will be those who decide to be a patron.
The other argument is that piracy cannot be stopped anyway, this is the internet and you cannot force your will onto others (and you will not be taking legal actions given how you are illegally monetizing other's assets and IPs). Your petty threat of cutting development is just that, petty, we all know you won't do it. This project is too profitable for you to drop it. And we have seen from CA1 how in the end you were just dragging the development for as long as you could implementing minuscle monthly changes just so you could squeeze more money out of your patrons. That was super greedy and has lost you ALOT of goodwill.
You are still charging an arm and a leg for this project so complain as much as you want but I don't believe for a single moment that you will drop it.
Now comes the suggestions:
you are targeting the english speaking population (given your MTL localization), and that is most likely due to you wanting to reach a bigger market (for monetary reasons). If you are doing that I think you should at least learn the language. Right now your english is broken at best and you are depending on volunteers to help you make your game. I am chinese myself and know the difficulty of learning english but by putting in effort and improving you demonstrate that you at least care somewhat about your western fanbase and they are not just your cash cow. That is especially evident since you have not improved a single bit since CA1, and that was what, 5 years ago?
(I know you wont be reading this since this is a wall of text but I honestly hope someone will translate the meaning and convey it to you).
The other thing is less important, since there is a hacker willing to crack your game, you might want to remove your online DRM, right now that is only making you patron's experience worse and costing you money, while the pirates gets an arguably "better" version.
People would sympathise more with you and your struggle as content creator if you stopped your mercantilistic practices, and like many other creators, if you can't fight piracy, you might as well embrace and make use of it to promote your product.
