Been playing this since it launched off and on and it's changed quite a bit. It's on patreon but the guy releases the newest version for free a week or 2 after for those people on Patreon and he does monthly releases. You can choose your gender. The RPG elements are easy to grind out and new skills are learned by using the lower tier of a skill until you unlock the next one as well as some are obtained by collecting some pages from a dungeon or other trainings. You don't have to use the mind control to enslave the girls nor do you have to enslave the girls in general.
