Before I start my critics: I really love the direction, this game is going. I'm also a big fan of "Second Class"!
But you asked for opinions, so...
As you wish to attract the masses I think some more story and goals would be desirable. "Second Class" was in fact better in this regard. However I agree that a lot of text is not the way to go.
For me the events come way too fast. There is no build-up of tension. There also should be more teasing before the events.
If you haven't already played I recommend playing SummerTimesSaga. Even if you're not into this type of game (I myself don't liek 2DCG, mega big boops, ridiculous big penises and so on) - the story telling is excellent and a lot of fun to play, sometimes I even did skip the sex scenes to be able to continue with the story.
And I think this is the main reason, DarkCookie is the most successful adult games writer on patreon, according to

I'm dreaming of some real story like this behind the events.
Also graphical it's mostly long-shot. Think of making a movie with different camera angles. If people are speaking, focus on portraits maybe? Zoom-in to her body parts. Be more creative with the camera.
Think about a sex scene as an own story with prologue, teasing, tension-building, action, climax, ending...
My opinion is, that these points are more important than the question, if there is [fill with fetish someone doesn't like] inside the game.
I hope you understand my comments as constructive critic.
