I really liked the game. Most, if not all, of the other games I've played have never managed to engage me enough to actually read all of the dialogues and actually feel immersed. This one was an exception, and a pleasant one. GF seems very natural in her reactions and writing, and the sister is a bit over the top, but I guess she can pass.
I have played the entire game choosing GF and avoiding all other women and so far haven't seen any NTR content (thank God) so I'm not sure why it is that some people get some of those scenes. That being said, I did receive a HJ/BJ from the hypnotist's sister at the party and, just out of curiosity, is that scene avoidable?
