Because I'm terrible, I had to "learn" how to make websites forcefully lol. The mere fact our website works it's a miracle.Why don't you charge on your official website and only free content after 1 month? (E.g.: whoever pays will get information and the game version this month, and after 1 month the information with that game version will be free).
You can try the Kofi site. I haven't read much about the policy site yet, but I see many developers here have used it. If you try to join, you should check the copyright, this is a parody game, and I'm afraid you'll get into copyright issues.
Also, I use those 30 days to make little improvements, finish art if there was something unfinished, fix bugs, update translations, etc. So, technically, the public version isn't EXACTLY the same the last private, it's more polished.
Ko-fi is nice and easy to use, I have an account there that I don't use, I read somewhere that they ban very randomly.
If things get better soon, maybe we won't need it.
