I feel like there are almost too many love interests, I'm forgetting who is who each update.
Yes, I think this is one of the issue with WVM. It starts strong with a handful of girl that all have their own personality or at least their own shtick and motivation. But as the game progress, it just throws a myriad of girl at you with barely any characterization and doesn't spend any time digging a bit for you to know them.
The last couple updates (9.5 and before, I didn't play the 0.10 beta yet) were particularly bad on that matter. You're constantly interrupted each time you start a meaningful conversation with a girl. Someone barges in the room, urges you to talk to someone else, and as soon as you begin to talk to that other person, someone barge in the room, urges you to talk to someone else and so on, rinse and repeat). You end up with a ton of the "new girls", that are completely lacking any personality. Most of them are just completely infatuated with the MC for no real reason and have no real motivations of their own. To me (and that's merely my own opinion), many of the newer girls feel like cardboard cutouts, with copy-pasted personalities, who only differ by their 3D models.
Don't get me wrong: I'm still glad to see new updates, renders are as good as ever, and I'm glad to see people enjoying it. I just wish that the author would spend a tad more time focusing on the existing girls before throwing even more at us.
