I find the sanity mechanic a little confusing. The tutorial says being at 0 sanity is supposed to change somebody's ability. Is it meant to just change it to one of the other ones you can buy? That's what I experienced, at least. With how difficult it is to hit 0, I expected something a bit more unique. Also, there's an item that gives a large buff if a character is at 0 sanity, but having a character at 0 sanity fight makes the game freeze up. Am I using it wrong?
Another issue I've had is that after a couple runs, I stopped getting any solo character scenes. I thought it might be related to the 'lead girl' thing, but no matter what I try I only ever get the duo scenes showing up.
