The game is pretty much linear, all the girls are basically forced on you. I think people dislike her personality, or perhaps they viewed her as an obstacle for Leah or something.
It is very linear.
My issue with Karina is more her being so naive. I'm not interested in teaching someone how to be a lover.
My main girl is Mel anyway so being an obstacle for Leah isn't a problem.
This update pretty much hit the nail on the head with why I don't like Karina much. She wants to fit in but she doesn't. That song, one of these things is not like the others, that's Karina.
She is your friends little sister that has been forced to tag along with you. Sure some people like that but it's not my idea of a great character or potential lover.
Not a dig at the devs, nor would I want her removing. While I don't find her to be a potential sex friend I do think she's added quite a bit to the story especially with regards to Leah's character growth.
I think it's safe to say that all paths in this game lead to a harem.
Not really. Things are starting to develop on the feelings front, especially this update with Alice and what Melody said last update.
Chances are it will probably split into paths at some point and not all of them harem.
