I don't know how big Madek's team is, but one option could be removing "Two Weeks" from Patreon, and create a website of its own, where you could then purchase the game/updates via BuyMeCoffee i.e. and then on Patreon have a different game in production, it's what MrDots was forced to do with DMD and Melody, and it works for them nicely. Then just come up with a production cycle, how often would update "Two Weeks" and how often the new game.
Like I've said, I'd absolutely love "Two Weeks" being continued, I wouldn't mind at all if it would see an update only every two months or so, so long as it is being continued, I've been a fan of it since the beginning, always saw the potential (love the models, the art, the atmosphere, the story, the dynamics and build-up), and so does many other people, I'm definitely not alone in this
