This is a very nice game, though I haven't finished all the content yet. Art is cutesy and hot, story is interesting, dialogue is good which is very refreshing for a porn game, love the bar tune, those hours you spent finding music certainly payed off. I do like the bar minigame, although so far it's a bit restrictive - there seems to be a single dominant strategy that is best for every skillset. I think more variety thrown in via randomizing patron reactions and wants would be good.
My question to LJG, have you ever considered a parallel, more dominant route? There's a whole bunch of femprotag games on the market and they tend to fall into the same exact trope - heroine is either meek from the start or gets broken and eventually corrupted to the point where she becomes a mindless nympho. Which can be appeal for a lot of people for sure, but it's been done so much, and in my opinion, the character loses her appeal at some point after her entire personality shifts toward sex and nothing else. They just become fucktoys and that's boring. I do appreciate that your corruption route doesn't seem to lean too hard into it, else it would be pretty much exactly like any other femprotag game.
What if there was a separate route for Catherine to explore her sexuality and her desires, but instead of getting brainwashed into it, she does it on her own terms, and continues doing so even as she becomes more and more depraved. There's a plethora of basically unexplored themes here. Domination, manipulation. She runs a business and she could potentially become as ruthless and cunning as all the other girls on the rooftop and beat them at their own game, by using sex as her tool. Nothing would stop her from still doing all the tittilation, teasing (and more) she does at the bar too at that point. It could potentially shift her dynamic with IO too, in a way where she holds a lot more cards in that relationship. Just a thought.
