Understandable. But especially with Patreon and co, you have to keep people entertained. I don't think anyone will be upset if an update isn't fully finished, or if something is changed in a later update. It's a process, after all, and mistakes are part of it. But people also need to see what's happening and, of course, want to test the updates and give feedback. Otherwise, you could just finish developing the game and release it.
I think I bought the game four months ago, and there hasn't been an update yet. I was also on your Patreon. But the promise of an update doesn't keep people interested for long. I would have been happy to test out even the small improvements. Mechanics or story aside, there are many games that change content later because they weren't well-received. But that doesn't mean it's a finished game yet. not everthing has to be perfect in an process ^^
