There are plenty of games that take much longer than this one in between releases. Just because early on in the development cycle the dev released very frequently but no longer does, that doesn't mean that because this last one took awhile to come out it's as good as abandoned.
And again, even if this were eventually to get abandoned, talking about that after only 2 weeks since the last release is ridiculous. It doesn't matter whether you were satisfied with the last update or not. It doesn't matter if you have trust issues with the dev. Basic logic would dictate that, since almost nobody releases in 2-week cycles, it's unreasonable to expect another release already. (I say "almost" b/c I have never seen it in following over a thousand games for years.) Logic would also dictate that, because a release just happened and so clearly the dev is still working on the game, there is zero evidence that this is going to be abandoned. You can feel however you want, but it's illogical at best.
