Let me start by saying that i've also read Dagashi Kashi, and i think call of the night is an improvement in terms of both the visual narrative and narrative structure.
Now for the elephant in the room: the ending. The compromise reached at the end was seen a long time coming; it was either that, or straight up never seeing one another again. And it was quite evident that the 'bad end' (turning into a complete vampire) wasn't going to happen.
I can understand some people thinking that this was more like the 'end of an arc' instead of the manga as a whole. We don't know if there will be a timeskip sequel, spin-off or something of the sort. But for now i'll assume it's a done deal: I still think it was successful in what it tried to do: a coming of age story; with enough imagination, the readers can imagine how their relationship pans out in the future (surely not as a typical vampire relation, but that's what made it charming in the first place, right?)
That being said, i don't know if i could recommend his future works. It might be a pretentious, even unfair critique, especially considering how a lot of manga have been drawn out to hell (modern example being kanojo rental) but it's still something of a weak point in my opinion. For what it's worth, in these scenarios it feels like less is more, and something that would greatly benefit his storytelling is cutting down on some of the fluff (just some, not all).
Still, being under 200 chapters (around 5 years runtime, give or take?) is still what i consider reasonable, so this gets an okay recommendation from me. We'll see for his next work, maybe i'll just be trapped by his excellent character design once again, who knows.
