Not far into the game, and these are my minor gripes so far.
I ask that you add more themes, particularly look at themes used for IDE and programming text editors. So players can have ease on the eyes.
Maybe a way to stretch to the browser, since as of now it has a lot of empty white space.
Control of volume/sound. When a video plays you can get hit with very loud sounds out of nowhere. Maybe look into Apocalyptic World's code on controlling the volume of videos with a meta slider.
Minor bug. You can continue to get stats as long as you don't press green check mark. Example. Start a new game, go to parents bedroom/bathroom and talk to Tara, then talk again without pressing the green check. Keep repeating (Time sometimes passes, but it is hidden). As an aside, I think the tutorial on interacting with NPCs should happen the first time you encounter an NPC instead of a bit later.
I would suggest to have a colored outline for when a class has a lesson.
Also the MC's kitchen should attach to the dining room, it is weird the lounge does but not dining room.
Would be nice if you could reset the room without leaving. Like talk to one person then you want to do the room thing like a lesson, instead you have to click off of where you are and you may not remember exactly which room it was. (Since the green check mark isn't actually necessary, it is more efficient to click to other things and do their action, but without it the time/action doesn't really update. I suggest making it mandatory or removing it.)
A larger photo when you click on someone to make sure they are the one you are interacting with.
If you take sister's panties, and place them in wardrobe, you can not remove them from it without wearing them, instead of straight to backpack.
Also really need to add jerking off with clothes instead of just wearing or not.
Things not being purchasable are fine, but it would be nice to know their price.
The overworld map should really have "boxes" around places to show that these are locations.
Stat changes needs better readability. Example is compliment someone and their Sub/Dom stat gets a +1. Which one changed? Or going into Gia's room early morning when she changes, if you interact you get a +1 like of Gia and -1 like of sis. Without info and control players can't really play the game the way they want.
If you store books in your room, you can't read them from storage you have to move them to backpack. Why?
