Ah it's okay. I do like the cg's. I did realize that time was pressed, and NaNo is super hard to finish the game. As for the extra characters, they did fit in a way. You picked good art to match the main game =).
As for Izumi, it was when he mentions his family, but then tries to not talk more about them. He says how he doesn't always get along with them either, and that got me thinking. . It was sometime in the common route, and was the first time he talks about them. I just had a feeling. Also, him having that expensive apartment really nailed it for me. It's not bad though. I did enjoy his route =). I've just read a lot, so sometimes I'm able to guess where the story may go. As for Souma, I still liked his route. Did you guys just really like Izumi? That can happen when writing characters, we love them so much that we just wanna write more =D.
And np! It was a fun game. I really enjoyed it.
