I'm going to assume you mean Patreon and not Caribdis themselves. And that is not how it works, you have to spend money for them(Patreon) to make money. You can view like the first 2 -ish lines on the articles to at least know what the post is about without even paying a cent.
( Edit: Also note, Patreon is just one of the platform they use to make and fund the game(s) soooo)
Caribdis also post frequent updates to their discord server. On the the last post made on 2/15/2024 0.7 is 89% done. If I had to take a respectful guess I say within the next 3 months give or take it will be finish. That's depending on their schedule and any unknowns.
I would prefer to keep it here on Itch. I dont see what so wrong with that? Why cant Caribdis offer a little more information here on Itch?
My thought on it is that he's trying to draw people to Patreon or Subscribestar because they are more easily monetized. Monthly subscriptions dont seem to be a thing on Itch.
I've said this before, I have donated money to Carbidis for Eternum in the past using Itch. So why cant I get some of the same extra info? I dont expect every benefit, early access for example.
Mainly I want to know when the next release is due and I understand that a % based progress bar is on the Patreon page. Why not on Itch?
I have seen other developers give consistent reports on a monthly basis on Itch, so I know it can be done.
