Not to disregard statistics because they do matter to some extent (particularly hours of play, more importantly hours / word count per route), but above all else for me by far my values are the quality of the writing and whether or not there is at least one character ticking a lot of very, very specific boxes for me. Massive bonus points for features such as His Point Of View scenes/events/recaps (DLC?), and the extent of customisation for the personality dynamics and behaviour of the protagonist to influence events to play out in ways that most media would typically never go down the path of. For example, avoiding silly conflicts, or having matching personalities instead of opposites attract or other types of clashing, and especially having combinations of 'unusual' personalities and how these uniquely influence interactions. In fact, having choices offer options to speak through actions rather than words is one of the most effective possible interactions to me, especially if there are multiple actions. Even saying and doing nothing whatsoever is brilliant, just to see character reactions, especially if this is more effective with some characters than others. This game's visual protagonist customisation options also tie into this. These factors are rare and valuable to me, so I would be much more likely to pursue these aspects even if the game was to lean more towards being comparably short and sweet. There are one or two certain studios whose writing style, character designs, character personality and relatively few but extremely effective CGs have me absolutely running to them and actually make me wish they would charge higher prices because they deserve it despite the short hours of play per game, their content is that amazing to me. (Especially because it's extremely rare for me to have any interest in more than one character's route in an otome, so that is absolutely astounding on top of the quality.)
On that note, hours of play should probably not be forcibly elongated if it isn't a natural fit. As I'm sure we're all aware, that just becomes a slog for developers and players alike. In a similar vein, I would much rather have multiple routes (a la 'stay' and 'non-stay' routes in Alice in the Country of Hearts to co-inhabit or visit a character) for a handful of high quality characters as opposed to being swarmed by an onslaught of orbiters I can't abide. Of course this also shouldn't be forced. (I have yet to find time / work up the courage to try this game's demo so have been lurking all this time simply observing the development logs, but I'm sure these characters are perfectly bearable, and it's always good to give players options. Admittedly, using many character roster slots to get the vanilla usual suspects out of the way ultimately gives a better chance of me liking one of them if developers eventually hit that point of "Well, what kind of guys are left? Throw everything at the wall.") Also thank you for offering the option to have playthroughs without being forced to latch onto anyone. This is generally ideal and especially useful here in waiting it out for a route you actually want. When it reaches that point, I'd be even more willing to pay higher for what I actually want.
Apologies for the wall of text and congrats on reaching this point. From the development logs alone I can see the effort you're putting in, hang in there. Above all else, absolutely charge a higher price than that. From what I can tell you have definitely earned and deserve more.
