1. Right now there aren't too many femdom scenes and the femdom stat doesn't affect much. There are plans for having more content "gated" behind stats, but I feel like there should be enough content to play through without it feeling a grind.

4. I'll be releasing the next update as a beta on Patreon/SubscribeStar today or tomorrow. If it's all good, it'll hit public release in a couple of weeks.
