I just discovered the game about a week ago and have ploughed through it (*snicker*) in no time.
I really, REALLY enjoyed ep9--probably more than any other section of the game. I was dreading it a bit, assuming it would just be absolutely drama-filled after ep8. Having a good chunk of it as one really big fun event with myriad possibilities of interaction was a relief. I think it was the perfect balance between meaningful plot movement and casual free roaming. If you play with the mod on so you can have all 5 active relationships throughout the night there's a ton of content.
And, fucking bravo on the scene development. I can't speak for anyone else because everyone's into different things, but being a fan of (read as 'obsessed with')
every sex scene in this one was hotter than the last. The animations just keep getting better, too--subtle hip movements and facial expression shifts etc. make all the difference between a good AVN and arguably the best AVN.
Not just ep9 specific but for the whole game itself, I very much appreciate that (as far as I can recall) it omits a lot of the AVN tropes like sleep creeping, etc.--things that feel gross if there hasn't been some sort of pre-consent between the characters.
I will absolutely play this episode over and over until new content comes out.
