I think you should improve the loitering content, (which I like) especially adding variety to how they greet you based on stats and what they're wearing.
Reduce the frequency of the washroom hall loiter, or fix them, they're lower quality.
Add some loitering to the bedroom hallways and the springs. These wouldn't need an animation.
I don't like the ropes as a standard option, mainly because its so silly. These things probably take 15 minutes to put on, and they just stand around in them? They would make more sense as a rare and random event.
I would like a topless version of one outfit, for each character. The bottom would be something relatively conservative, like the maid outfit for Kali, bicycle shorts for Maria, normal jeans or yoga pants for Ashley, a loincloth for Android, a long dress skirt and dress shoes for the twins, a black nuns skirt and barefoot for Autumn, and for Lin, not sure? some kind of leafy skirt that doesn't cover the panties
