We've had plot threads dangling for ages now! The whole "I hate being treated like a cat, except not by MC-kun, and also I let people treat me like one for hours at a time for money" thing is still just up in the air.
Ironically, one page per update actually liberates the author from needing to treat things in a more episodic way, just as much as it makes pacing and coherency a challenge.
In a more traditional multi-page update, you generally expect each update to be internally coherent - particularly if the updates are fairly long and with a slower release cycle (which is generally the trade-off you make). Each chapter needs to be at least somewhat self-contained, with reminders about past events and setup for subsequent chapters incorporated into the actual chapter content. Though of course lots of stories play with this, particularly when they're targeted at older readers - you can assume they have the capacity to hold more of the story in their heads and don't need as much hand-holding . . .
When you get a single page, generally only four panels, you're far more constrained in what you can put out in any given update, but that limitation means that you can basically ignore a lot of the "normal" requirements of episodic story telling. Jumping from one sub-plot to another is inevitable, leaving things hanging for a while is totally normal, no one expects things to be in a coherent state at the end of each update - that's all inevitable, so rather than worry about it the author can play with it instead.
From this author's previous work, it's pretty clear that they're quite comfortable with things like leaving hints about critical plot elements in totally random places, hinting at important background details with zero follow up for literally hundreds of pages, and interleaving sub-plots however they see fit. I don't know what level of fine detail they have in their overall story plan, but there's zero chance they could do any of that if they didn't have the whole overarching plot sorted out ahead of time, and important details about all the core story arcs and sub plots planned out
far in advance of actually drawing the relevant pages. Exactly how that plan translates to each individual update is probably less well defined - that's probably the biggest question mark about this kind of writing, because that's the biggest part of
pacing, and that's probably the thing that has most direct impact on a reader's enjoyment of the story.
I do think pacing is the biggest weakness of this story so far - it does have a tendency to jump between sub-plots a little quicker than feels comfortable, and leaves a little too much floating. But at the same time, we still only have around 180 pages - effectively nearing the end of the first book; the core plot might easily last four or five times this long. There's plenty of time for all those floating threads to be collected and tied together in a satisfying way, so it's really just a question of whether or not you trust the author to be able to reach that satisfying conclusion.
Personally, I do feel this author will be able to pull it off in the end, and I'm perfectly happy to follow along with regular updates (rather than leaving it unread for a couple of months at a time); obviously you or anyone else are free to have your own opinions. You're also free to complain about things however much you want, of course . . . but you clearly already know that.
