The characters get a first pass with a rough base to build from. Future updates will add to the content and flesh them out, adding additional build up, h scenes and other content. The family content has had multiple passes and updates to flesh out the stories more.
If you have any ideas or constructive criticism I can pass it on.
I'm going to try to limit this to two characters and their recent updates but this goes for a lot of characters as of late.
I'm aware that a lot of people think that the relationships of Mom, Sis, and your aunt are well established, but those grew over time. The problem is that Eric's is a horrible trade off and Mia's potential is being squandered.
Potential. As in expectation of growth. Eric's is going backwards and is a bit negative while Mia's (from what she had before this update) is being sidelined and going way too fast which leaves the person apathetic to her right now.
Lemme explain if I can... You know how you got cockblocked by Mia before this update? Or how Eric reluctantly went with you to the school as a sort of tradeoff for the video game (if you want to think it)?
We need more relationship building with the characters in general, these two especially. With the incest bunch (mom, sis, aunt) you already have a relationship that was terminated and you fill the void as the man of the house while also giving them some winky woo which all three haven't had in a while. But Mia seriously (IMO) should be the most cockblockingest religious girl this side of the Tennessee and for good reason. This is all new to her. She has a religious bias. I believe she should be a slow burn to getting into her pants. But the trade off should be that she's exploring her sexuality if you pick her. While similar to your sister, it should be that she starts exploring some voyeurism with you. Maybe she meets you in a class at school and plays hooky. How would that work? What would she do? Maybe go all the way, but a quick kiss and a hug are something she does while praying for more. Maybe you meet her outside the house at night. Because of the stress at home, she just wants to cuddle and kiss while you stroke her leg. That shows intimacy. I know, it'd take much more programming to get the slow burn to work, but my point is that she explores a different form of intimacy and sexuality that you can't get from the incest bunch or her mother.
I feel that her mother should be corrupted similarly but this isn't about her. I'm sure this is a first run through and most of it will be improved.
I feel that Eric needs more character building. His best came from the exploration of the school and I hope that there's more in future updates. But his update turned him into a whiny and lazy manchild unintentionally (I hope). He should be doing something that takes him away from the vidya for a second or two. A hobby or something where he can have some sort of redeeming quality. Don't get me wrong. Gaming is great. But if he has intelligence, make him a chess club member or something so that once a week, he's doing that. Let's say that he has a hot girl in the class he would like to talk to while Junette is interested in him. His quest should be to learn how to talk and that gives him a chance with two girls as he learns social skills. The payoff is that they investigate the school which seems to have secrets.
Now that's just one example. But if he goes into this fantasy world, I'd respect it more if he at least was trying to say more about how depressed his life is or something. He has a flaw which isn't being explained and it makes him look worse as a character.
Of course, this is just my view of it. I'm fine if they are changed to be characters as in a VN that go through their ups and downs, but as they stand right now, I think that the updates have left them in very bad positions which sours them to others.
TL;DR I think that both characters need a second look and more depth added to their characters to make them redeemable. As they stand, they're not believable as they don't have a lot to establish their relationship to MC and make them endearing to have as friends and qt gfs.
