020 includes the fight with Loretta and Camil, and both are stronger now.
Camil is pretty similar to what she used to be, she just has more attacks and a knockdown gauge now. She also hits harder, both in numbers and in the animations. Her breast pressure move, strangely, instantly knocks you down when you block. Seems to make things rely more on guesswork. Not sure if unintentional or there's a trick I don't know. She also has Lusy's tit hammer now, so I'm guessing Lusy will be getting a new move to replace it.
Loretta on the other hand changed a lot. Now she's a speedy character who tends to act before Alf does, unlike most of the other characters. She also lost her breast smother, probably due to the fact it doesn't fit her character now. I'm guessing Lusy or Sejna will end up taking it instead. The trick to her fight is pretty hard to figure out, so I'd bet most people will have a hard time with her.
Another minor thing added in 020 is facial expressions during conversation, which is nice. Camil looks surprisingly cute when she smiles.
I think that's all there is to this update.
Small quastion: how many characters in this game actually insult Alf's penis? And is Camil one of them?
Edit: He also updated the character page for the maids on the homepage. It mentions more about them now. Hard to tell what everything mens, though. I did, however, notice that there's a part that straight up says that Lucy, not Camil, is the best fighter out of the maids.
