I think this update was a very good one, the previous one the story was getting very weird, and dividing it into two more distinct routes for the human/demon makes it work a lot better. The thief being a burglar that gets caught in our guy's house rather than a bank robber that he goes out hunting down like he was suddenly a Shonen character? Definitely fits the more grounded human route better.
There are a few things that I would personally like to see as the game progresses. First I think it will be good if the girls adapt to their captivity, and after being there a while stop crying etc. when he interacts with them. They should get used to it all after a while and become passive and docile.
It would also be great to see some changes to their bodies, them getting thicker and their tits growing bigger would be great, the human guy could do this to them with drugs and hormone treatments, plus of course he has control over how much to feed them, and the demon guy could either do the same or use demon power as well. He could also use drugs/magic to dumb them down and make them more cow-like, though he'd need to wait until after getting Eveline to do what he needs her to do with the police before he did anything mental to her.
