Those 37 days are since the last bug fix. There hasn’t been any new content for four months. And now another fix has been released—not new content, but specifically a bug fix. If the developer is having problems, perhaps they could let us know? And at the same time, give us an estimated release date for the next content update?
Your reply makes sense. Although, I notice new things, at least. I agree they are usually smallish updates, probably mostly bug fixes, but still some new stuff each time from what I saw.
I can't recall if I read the update on cluster or subscribe star, but the dev mentioned what was going on, though I don't know if I would phrase it as 'having problems.' Just natural difficulties with needing art done and such, and, I mean, in my eyes, seeing the changes with Subscribe Star and stuff, giving some space in respect of that is just right. And for your last comment, they do somewhat mention any delays.
I feel all your points are valid and understandable, though a bit harsh. Often some new content, the dev does post difficulties, and there are general estimates on some releases. Might just not be as substantial as you may wish for.
I also wish for more more updates, more info, and all that, but I'm content with what's provided since I feel that I see and receive more than enough. Also, an update released recently.
