I just played the updated demo and I have to say, it looks amazing! I'm so excited to play the final version. :) I'm sure I will love it just as much as Changeling if not even more. The characters all look really interesting and I love the customization and the flowchart as well. I've not played through all possible choices yet, but so far Jack is my favorite. One idea I had though - if possible - is to maybe omit some details about the characters in the bio until they are revealed in the story. For example, in-game Jack said that he is with that cult, but when I checked his bio, it showed that he was lying to me the whole time and that he is with Crimson. It's fine either way though because I enjoyed the demo regardless. It's just an idea I had. I don't know how to program so I have no idea how complicated my suggestion would be either.
Anyway, I look forward to playing the full game! :)
