Following a comment I got on a forum regarding my recent Conversation Simulator, I devised a new condition, which is actually the exact opposite.
Instead of trying to reach a specific topic in the best way she can think of, Kiyomi will now try to avoid it at all costs. But, following as previously, she will still try her best to pick a smooth transition from the topic you brought up. So she will do her best to come up with the best compromise between a topic that is close to yours, and one that is as far as possible from the target topic.
In termes of gameplay, it makes for a greater challenge, since unlike the previous version, Kiyomi will never ever bring up the target topic on her own. So you have to try and narrow down the "area" she seems to be steering away from to guess what the target topic might be. Once you know what the target topic is in the fixed condition, you can play around by trying out topics you know to be very close to it, and see how smoothly Kiyomi tries to steer the conversation away.
The links were updated, enjoy. :)
