I've played 0.3a, and as I said with 0.2, I'm liking the game, and all the drama xD.
The bad guys are still totally over the top. The father is a complete asshole, there's no other possible interpretation. He doesn't have a single positive aspect. Cheating is bad enough, but he doesn't even care about what happened to his daughters with that bastard Kevin. The guy doesn't even try to pretend that he cares...lol. Well, at least I haven't doubted it... divorce xDD.
I hope Ellie gets more fleshed out. Her "shower trauma" doesn't justify at all her rencor.
I like that the youngest sister, Sam, gets some development.
Regarding Izzy... wow, she sure is good looking for me. I wonder if, despite her standoffish attitude, she's actually genuine with Chris, too early to tell. I don't rule out that the the whole "doesn't let Chris touch her" reason is that she's trans and isn't ready to tell Chris... but maybe she's just manipulative. Or maybe there are other reasons. We'll see.
Be that as it may, do you have many possible endings planned? I mean, for example Chris right now could end up with Alex, with Izzy or with Zoey, but I don't know if the game will really offer much freedom of choice with Alex and the rest of the characters, or if everything will be more "predefined". Considering the divorce choice, which seems quite big, I guess there will be a good variety of choices for Alex and the rest of the cast.
One detail that seems a bit unconvincing to me is that some characters seem too infatuated with Alex. Let me explain: back in 0.2, Zoey clearly likes Chris. A lot. But the moment she starts to interact with Alex in a more "intense" way, it's as if she forgets that she also likes Chris. And in this new chapter the same thing happens with Chris: she's very horny for Izzy and wants to masturbate due to that, but the moment she sees Alex, she seems to instantly forget about Izzy and just thinks about Alex. They should, I think, doubt a little more, they're supposed to really like Alex AND other person.
