I don't really know 'Knight of Love', but a quick google search and graphtreon.com reveals he have not been around "for that long period of time" not on patreon anyway, he have been around since 2020ish, that's a ok amount of time but not really a long time. That said he also makes over 1000$ per month, and like you said he should perhaps earn more, and sometimes an increase in $ just come slowly over time... which it also looks like is what is happening->

This clearly tells a story of a small developer making a game a fair amount of people like, and it also shows he is making more, slowly and steady, moving up in patreons and $ slowly.
And now to Latissa's patreon

This tell another story, one in which the team did have some momentum in the beginning, but its clearly dropping, and that's probably because of these other things we just talked about... people are not happy with update speed and delays / promises not being held.
- The team already knows this, and they wanna improve, but its up to them to change things around.
I only think we don't agree on how much money 600-800$ minus TAX/VAT(which is 23%) will provide you. Which in Latissa's situation makes it around 500$ to my calculations.
