Heavy customization of the main character(s) is difficult with the amount of CGs and outfits we have planned, but some limited amount may be possible. With the attendant and other NPCs, we are planning on adding more body types in addition to other variations.
If we do something like body changes (i.e., breast or butt expansion) it would probably just turn into a scene with CGs rather than something reflected in the sprite system, I think.
