After taking a week off the development I feel amazing and have much more clarity of what I should be doing next.
After Level 4 of each character you'll get a choice to either go with Love Route(Pregnancy) or Slave Route(Prostitution) the Status window for the female characters would change based upon your choice and will lead to different sex events, Each girl getting pregnant would Increase Relationship with Sex maiden and her power will increase.
Also, I've locked Castle and Exploration(World Map) as they don't have content properly made yet. Keeping them in-game is just a distraction to players and might confuse them if they have content.
I'm also working with a music creator to make proper Songs for Special Skills.
Thanks everyone for your support a new version should be out soon!
