I actually really like the choice of Alice as the first target, as both an homage to the games and as a pretty structured story to use as the tutorial world.
I agree with what others are saying regarding love/spite but I think it's fine for now. Another way of doing it could be that high love means lower Sex/Lust requirements, high spite means lower Obedience/Inhib requirements.
Still this is real promising, and I don't even have that much fondness for the KH games.
Also I'm so glad I played it now and not when it was Pete, cause oof.
