I've only played through the fully consensual route, but I have to say that I loved how you handled the matter of consent. It was really cool to have characters actually talk through the issues when they needed to do so. Well done, author.
Question: are you planning on adding enough new content as to constitute new routes? If so, I'd be really interested to see how Kyou would react to the idea of being hypnotized and submissive himself. It didn't seem to be brought up as a possibility at all (even one to be dismissed) in the route that I played.
