I think the gigantic number of potential interests is a big part of that problem. It's basically forcing the script to only go down this goofy path now. The beginning of the game felt like it was headed a lot more places, but now the MC has 80 girlfriends and instead of developing them at all, he just keeps meeting new girls with shorter and shorter introduction arcs before they decide to join the swarm too. The only thing stopping the MC from being with every eligible girl in town is the developer taking 8 months to release five minutes of content.
I absolutely agree. The number of female characters is absolutely inflated and some characters are either irrelevant to the plot so far or interchangeable with other ladies without making a difference. Penelope, for example, has almost the same background as Shauna, except that Shauna and our protagonist have been friends forever. What Tia's plot point is, if any, no one knows, and Tali (that was the ex-princess's name, right?) is also a character that could easily be removed from the plot without it making a difference. Alternatively, one could simply put the characters into a sequel, then use the ones irrelevant to WVM 1 as potential LIs for WVM 2.
You wouldn't even have to remove them completely, but let them show up now and then, give the protagonist support to talk or whatever and then leave.
As it is, though, a lot of plot is left in limbo: what is Bailey's problem with explaining to Rainn about what's going on with the protagonist when he's ready to share? Was MC's father to blame for Ryker and Katie's parents' accident, and is this the problem he has with MC, or is it something else entirely? Does Katie have her own unscrupulous plans with the protagonist and is merely more clever than Ryker?
We can speculate all we want, but without any real progress, it's just spinning in circles, unfortunately.
