I've seen quite a few people complain about bugs like that on here for the android version. Me thinks there's something off about that version. Could be that your phone isn't agreeing with it. Who knows.
This happen in android and mac version. I was playing the android in blustacks because my cellphone usually cracks with this. In bluestacks works at 100%. Doesnt have any problem. Untill the moment after finish the Rika second history. Just after the werewolf night in the bar. If you try to go to the town on night. You will found Cecilia. And she will ask you what do yo want. After that the game cant continue. Doesnt crack. Is just like a dead end. A soft block. You couldnt choice nothing to continue and the chat box never changes.
