I'm gonna need you to be more specific on multiple LIs. Like, I respect if you're just trying to create some lovey dovey romance game, but here's the thing. I'm only going to play through your game once. (barring any god damn "your saves are broken" stuff, I understand it happens that rage is not at you)
So, when I play a game, I don't want to have to pick and choose who I want to be with, I want to be able to see as much as possible in one go. Now if this is one of those "You can fuck around with everyone and then have to pick one at the very end" it's not as bad, that's only 1 scene for each other girl that I'm missing.
If it's "You can only pick one to pursue and if you try to get with everyone you end up with no one" then it's not even worth the time it took me to write this.
Tell me at least that one of those multiple girl endings includes all of the "daughters", I think I can live with that.
