hmmm....I know what you mean, but I guess the devs wanted to be more than just a porn game and decided to go with that story, not gonna complain while it's a stereotype shounen story, I do enjoy those, and as i said before, this floor's mechanics are different because Karen is supposed to be a top boss in the top floors which our boi ethan is ready to fight yet so it's more of survival to win.
as for the h contents I hoped for more tbh (not much a fan of leather) but it suited her character i guess
as for the walkthrough...if you need help with anything just ask, I'll help with any way i can, you're walkthrough helped me a lot, I don't mind returning the favour!
p.s: it feels like Karen's scenes are a bit dark.....in colours i mean I can barely see lol
