A neat little game. The art is gorgeous, and I just love the look-around effect with the parallax backgrounds.
But the story is kinda bland. Unless it is a personal story, it feels like something is missing. If this was a properly told story, the only justification for making the instant leap from "we started dating" to "we married" is when you want to focus on something which happened during the marriage (which is somehow tied to the intro, otherwise it wouldn't be necessary to have the intro at all).
But that's where the story ends. If you tore down the visuals and left nothing but the transcript, it couldn't stand on its own.
So I checked the original The Question and it made some things clear. You didn't exactly make a lot of changes in terms of the plot, right?
For the example project/tutorial, it's perfect, since a) it tells about creating a visual novel; b) it's short and simple in order to showcase just the core mechanics; and c) the story is bland and vague enough to let people expand or rewrite it in any way they want.
For any other reason, it's ‘meh’.
So, as a ‘proof of concept’ – yes, it's a neatly polished example project; but I hope you plan to create your own, more interesting stories in the future, too. Good luck.
