If it helps make the "in development" thing feel better, I've been at this consistently for over a year. I don't expect development to get any slower than it has been unless mental health issues start popping up but I've actually been going in the opposite direction (feeling better) the past week or so compared to the previous couple of months. Obviously nothing can be guaranteed though, and I don't blame you for being wary about it. Honestly I'm not crazy about the whole early access public development thing but it is the current best structure for independent development in this scene.
I'm curious what certain story that might be though, especially if the answer turns out to not be 303.
