I'm glad you like it, and sure, for now I'm using magicka cloth2, but I will definitely also check out the dynamic bones you suggested,
Now only Yasha has breast physics and this was only introduced about 2 updates ago, because I only recently started working on it, I'm still learning it, not much is visible due to the lack of proper animations yet, only in the scene where she reaches out her hand to us her breast is pushed by this gesture, each subsequent character that is not flat like Eli will definitely have some kind of jiggle, maybe not perfect yet, but I will keep working on it. Old characters will get it too, of course.
I know it's important, just like jiggle thighs, tongue or other future elements for a girl like slime, kraken, octopus,jellyfish etc.
I'm just learning it, so it's not that great yet but it will be better ^^
