I feel like this game is going to be a miss. It require of you to have a monster PC to run it, yet it offers very little of the actual gameplay, even while taking those development promises into consideration, to justify use of real time generated 3D environment.
At current point this game is going into direction of being "your perfect doll simulator and kamasutra viewer" with, currently, rather stiff movements on those poses. Story and introduction of characters are simply unnecessary for this.
If developer is hardly using 3D enviroment instead of using it hard then it is just wasted opportunity.
Also, using 3D is generating a bit greater expectations about the game than simple visual novel.
Using pregenerated graphics for Visual Novels for this kind of gameplay and story would be enough though.
Still, it's nice if developer is trying something new instead of sticking to good and old working stuff. And I hope I'm wrong and this is going be great game, even though currently it isn't going into that direction.
