The main problem with this game is that it is too linear. You can't access other apps, choose who you're going to chat with, who you're going to go with... For this type of story, it would be interesting to have a game that was more open to the players. Sometimes, you want to focus on a specific character, but the story pulls you towards another character. Most of the time, you'll find yourself skipping text messages and making choices that don't have much of an impact on the story.
The content is heavy, involving incest and rape in a more realistic way, and it's a game that shows a girl in a vulnerable situation being blackmailed by her brother and her own father, forcing her to let herself be used by both of them and, over time, being used and abused by more people. It's definitely not a game for sensitive people.
