well devs with monthly and shorter release schedules have spoiled many players.
Consistently releasing on a tight schedule to reach maximum QUANTITY seems nice till one realizes that it burns out the people producing (the author in the case of this game here), for the project never to be finished in a satisfying manner to anyone.
I don't know about many devs with "monthly and shorter schedules" with the same high-standard output on the same media. We'll have to compare lists. To me the schedule of this game has seemed very reasonable so far.
In any case, I'd rather the author keep at what they've been doing, and that's focusing on QUALITY. Given their credentials, that's what they themselves seem to enjoy, what they're obviously good at, and dare I say expected to do since that's what most of their fans (especially the paying kind, I guess) play their games for.
Finally, there will always be a crowd that cannot be pleased, so yeah ¯\_(ツ)_/¯.
My best to the author, their ongoing endeavour and my gratitude for the very enjoyable game(s).
