I have NEVER had a book hangover so much. There are few books where I relate to the characters so well. I finished it 3 days ago and I still think about the character arcs. I relate so much to Zack and I'm going through his rollercoaster of emotions through his story - omg I was crying more than I'd like to admit. I'm really toying with downloading the v0.21 to finish the story or ride the hangover a bit longer in anticipation for the next update.
You have an amazing gift for storytelling. Thank you for sharing it with us. I can't wait to see what journey you take us on next.
