Very cool! Some thoughts I had while reading it:

Sex Move, why does failure move you two ticks while success only moves you one? Why not one and one?

Darkest Self: How it can be ended is sort of unclear. Just being physically stopped, that's all? It seems a little...uneven that a tall fence could potentially be all it takes to end one's Darkest Self. I'd go with something that more actively involves other players (as at least one potentially way to end it).

Moves: Some cool moves in here, but they feel like they could use more potential benefits of being in the Overwhelmed end of things. There are a few that benefit from being In Control, but unless I missed something (possible!), only stronger rolls in Strange Aptitude get a benefit there.
