To release the strange symbols, you have to turn the tables "against" Alice in the bathroom... if you know what I mean 💀
Well, I only did it once ✋️😑🤚 because a friend of mine said it was like that, but I didn't look at the protagonist's cell phone, but it must be possible since all the scenes are available after doing them, but if you skipped the Alice scene or did the scene where she is the dominant one, there's no way to get those scenes, I had to play everything again because I skipped the scenes with her the first time 😑.
