If this is supposed to be a game then it needs to have meaningful choices. The decisions made are supposed to show as the character being good or bad but in reality there are very few choices that have any impact on that (and none of them in the 3rd update). Just a very disappointing update in terms of story, overall the renders and animation are great but the story is being neglected. The younger sister, Daisy, deserves to be punched for her behavior, she groped the MC while he was sleeping, flirted with his girlfriend, and then felt her up in public. Feels like we're going to get unavoidable NTR content where Daisy seduces Amber and the MC is going to be "cool" with it.
Essentially in this update you make the decision of who to talk to first (you have to talk to all of them) and where to cum. It would be nice if I could choose to argue with Amber about the fact that she didn't seem to have any problem with Daisy molesting her under the table. Or perhaps the ability to decide to yell at the younger sister about the inappropriateness of her behavior. Instead the MC goes home and has sex with Amber on the family couch in the living room (what an idiot). Also, as a non-foot fetishist (are there so many people who love feet?) I would also like to see a choice to avoid the footjob. I understand I seem to be in the minority when it comes to not enjoying feet.
