yeah Jenny is finishable. Do the quests you can and you should be able to unlock that.
I've fucked up and locked out of Lucy 2nd game over scene, since replay only leads to fucking her when she's drunk. No option to fuck her tits no more.
Any ideas?
When you say "Jenny is finishable" are you really talking about Liza? I don't think there's any way to progress with her. I'll also echo what others said about the update being broken, or perhaps stuff before it. I tried to start a new game and think I actually unlocked content I didn't see before, but other stuff seems stuck. I think the game depends heavily on stuff being done in a particular order, as others have also mentioned. For Lucy, I think you only get the option to fuck her tits for a while and then you can't go back to it. As it stands, in my replay I think I blocked myself from the drunk sex route although I had that on my first playthrough. The in-game walkthrough also seems very buggy this time, not really accurately showing what quests can be advanced or not. But at least we're seeing more updates.
Edit: Keep forgetting that I have to have Lucy change between dresses to get different outcomes. The game is still very confusing, but then again like everything else on this site its a beta, and we have to consider that the game it was based on was even more confusing.
