The amount of onscreen girls might be fine if there was more places for them to be spread out across. As it is they're usually all squished into one or two rooms all the time. If Oni threw in a library, maybe a second classroom, those sub basements and lake Rogue loves mentioning, or let the girls go off to the mall on their own it'd be less crowded. Plus it could add unique interactions. Under the table blowies in the library, peeping on/walking in on girls in the changing rooms of the mall. Maybe a bathroom so you can bang in the stalls, and you get the option of quieting down when people walk in or continuing to slam at full force.
