This whole game is pretty amazing, however I did find myself pretty disappointed by the ending. Not because it was short, I understand why it's like what it is, but because two of my favorite characters have very disappointing endings (Succubus and Katelyn). Both leave no matter what you do, and Katelyn isn't even present at the end party to talk to. The Succubus leaving even if you choose her as your lover was quite shocking, and more than a little saddening to be honest.
Other than that I really have nothing to complain about with this game except that I feel there's not enough Katelyn content, but I understand as she's fairly new. I was pretty disappointed she had no pregnancy path though.
I'll definitely be keeping my eye on the changelog of this one, but as it took me over 40 hours to finish I doubt I'll be replaying it any time soon. Not without added content that I'm interested in anyway.
