Well, I don't think you're very close to something like that if I'm being honest..
A game such as yours needs to have at least 10-15 ways of punishments (it's BDSM, after all), and maybe about 5-15 positions of sex.
The quests are right now just 'time-wasters' as far as game time, and, while I don't expect them to be very 'profound', I would say that if that's the sort of quests you're doing (which I'm totally ok with) you're gonna need to have at least a few dozens of them so your game would keep up..
Also - you need some work on the animation side, and the environment does need work.. specially in the city's outskirts.. You made Rome into this tiny little market square and a desert.. The game needs that feeling of 'vastness' in the environment that is nowhere near here..
I really like this game, so I'm allowing myself to 'critique' it like this, so hopefully you'll take my comments and make this game ready for a release
