Oh woah, I didn't see that this thread had gotten any updates until I saw this comment popped up in my email notifications.
5 years later and I still think about the manga a lot, but it's not in active development.
Since then, I know now than what I did 5 years ago and do's and don'ts and what to do and what not to do
After I made the post I had a few manga pages drawn for me, I did not draw them, I had commissioned all the art and the 4 manga pages.
Since then it had allowed me to rethink about the direction of my story, and how to approach it differently in terms of getting work done and feeling the theme and such in the story.
