An explanation on how the level/stat system works would be nice. Since everyone has 10 HP, 10EN and 10 Mind regardless of stats and level.
Enemies starting at lvl83 and minions at level 100 and 200+ ... big numbers don't mean a good system. Personally, I'd tone down the levels and make them matter more.
Let's see, what else...
- enemies orgasming having an effect (either a stats like "weak legs" or something that gets more intense with more orgasms) OR enemies fall down and can be captured after X orgasms.
- a way to affect character relationships (between minions). Having sex improving it would be nice.
- a way to affect character likes. Nothing like using a VERY expensive sex position book on a minion only to find out they hate that position.
- perhaps instead of assigning a character to a specific room (with exceptions) you could assign them to a job and they would move from room to room as needed. Like for example, assigning to farming would have a character move to a farm, work there a bit, then move to the next farm, etc..
- Mess/Dining Hall room. Minions would occasionally take a break there to relax and mingle.
- Jailers actually feeding prisoners. If they know sex moves, they could "torture" them when horny.
- when futas are in - pregnancy for new minions?
