Well it looks like it will be an entertaining game, and the story although vanilla at the moment, did not bore me, I already have my favorite girl, THE LITTLE SISTER.
If I only end up with her, that's fine with me.
I did not find the other sister interesting at all (although she is very pretty). And she probably has a boyfriend, or a male friend she goes out with to have fun.
The same with the mom, I was not attracted to her, although we only saw her for a moment, you know first impressions are everything.
I see more potential in the cheerleader, who I hope is not a total whore, and what we saw during that, call was because deep down she's secretly attracted to the MC. will see...
We didn't see the aunt, nor the cousin and neither the stepsister, so who knows.
Dad's new girlfriend is attractive, but that path is already going wrong from the beginning, for me at least, if I can avoid her I will.
So in the end, two girls, the younger sister and maybe and just maybe the cheerleader.
The MC is not too bad, he's smart, and at least he doesn't have one of those stupid hairstyles, although it seems to be a bit on the weak side. But the good thing is that the dev gives us the opportunity to peek, or not....
(for the moment).
Good luck with your project dev, I wish you a lot of success.
