I am fascinated by this. I'm enjoying it as much as I can before the host takes it down, which I'm 100% certain will happen.
The game does demand a certain very clear, instructive writing style from the player. It will repeat back what you feed it, so it's useful to say things like "I know you feel ashamed when I spank you, because it's a childish punishment for a boy your age." Now the game knows it's supposed to be ashamed, and why, so it will respond better.
P.S.: Their NSFW filter seems to be a simple word search, so if you don't use certain words, it doesn't flag your text. This requires writing like an old-fashioned romance novel, with lots of euphemistic synonyms. The system will react if I have an "orgasm" while giving a spanking, but it's fine if I have a "symphony of pleasure exploding in the center of me."
