You should really work on getting the individual body part growths for the non-Frieren characters working. I can't imagine it'd be too hard, relative to creating entirely new girls, since it's just removing parts of a model/animation or whatever you call it. It seems a bit misleading that the single girl that is available free is also the only one with the individual body parts being split, which could lead to people who only like, for example, breast expansion, paying for the fancier versions with the assumption that the exclusive girls also have that feature. I'm sure you aren't doing this intentionally, you probably just wanted to make sure the first girl got all the features first so that free players could get an accurate idea of what to expect, so I figured I'd let you know.
