we, the people who do not have the money to buy your patreon, need more content!
It's been around 3-4 months
The Patreon is for sneak peeks, WIPs, non-canon art and some more exclusive little details, not regular updates, so you're not entitled to any of that. There is one huge update coming out every couple of months which you can find out about on my Twitter page when the time comes, and either subscribe to the Patreon then, or be patient for the public version.
tldr; Patreon content is very much optional so no need to be salty about it, you're not losing out on the main game.
You got mad for not affording Patreon content without taking a second to check if that content even exists, then decided to instead use that time to write a demanding comment about the non-existing updates. I'd say I approached your comment with the right amount of professionalism and explained everything thoroughly.
