So, this is a game that is currently under development and I have been following his work for quite some time now. He just released a new blog post and there is something in there that I think you guys would love.
"The Others opponents will have some specific feature as well.
One of the opponent will raise the arousal level of Kyoko just kissing her thanks to her aphrodisiac saliva. Kyoko's arousal will have 5 different level and any time she got an orgasm she will take more damage according how high is her arousal."
I really can't wait to see her in action!
