I agree with almost everything you said, and if my post came across as, "EVERYBODY PANIC!!!!" then I certainly apologize, that was not my intent.
As I said, the lack of communication is not a good look. I think it's going to cause Nverjos to lose some pledges from patrons, which is unfortunate. I am not attempting to encourage anyone to cancel, nor am I trying to suggest I know or even think the project is dead. All I'm saying is we don't know what's going on, and that's exactly the problem.
I haven't been following this game for a super long time, but for as long as I have been, Nverjos has posted about once a week with at least something. Regardless of what other devs do, this is at least a bit out of character behavior for this dev, and yes, I find that a bit worrisome.
