One thing I'd recommend, make the game the game as interactive as possible, tiny things here and there add a lot, like maybe having the girls say something or make a noise if you click on different parts of them. Stuff like the clothing system you're adding seems like a great addition for player interactivity, would be cool if other characters could comment on what they are wearing.
Too many of these games are all mindless reading, and the girls just stand in their bedrooms like statues waiting to be clicked on so they can spew dialogue. Even having a few idle animations can add a huge amount of life and personality.
I'd probably go all in on the choice between domination and love. Being able to choose the MC either being a complete violent bastard or a conflicted father figure. Definitely would love to see more kinks, considering they are slaves, the choice to be rough with them would be appreciated.
Keep up the good work! Don't stress too much, you're doing great
