I don't know if any one suggested this. So here goes.
Update physic for characters models (female) and partners model (female)!
Right now we have some part like arm clothes or hip cover that moving (animation) when characters run, walk... and the hair swaying around but the biggest thing is not animated.
The female characters chest/boobs/breast.
The princess has big breast, Ibaraki Douji - the cat girl has huge breast and she like to squeeze her breast with her arms and lean forward when excited. Kaguya has big bust too.
Last but not least, the female character has big boobs if using Glamourous female body or Slender female body or Average body female.
Look at them running, fighting in the game and their huge breast just like dead fish. Really? this is 2014
when clothes got animation, the body should has the same "detail animation".
Look at Ibaraki Douji and her huge breast didn't move whenever she animates... this feel so out date.
