I think this is a really cool project, been following it for a while now. I myself doing a turn based strategy game based on the 7 deadly sins. Though it was strange and interesting seeing you deviate from that, but I think the description of the project is a little bit silly "8 demonic factions that each of them represents one of 7 Deadly Sins." By logic, it doesn't seem right to say 8 things that each are represented by less than that.
Make what you want of it, but in my journey I was also doing silly stuff and I got corrected by people carrying about my project and I really appreciated the improvement in the long run. Keep up the good work!
