Yes and No. When she reaches 0 health, she orgasms but she also releases her soul and dies.
But killing the treaters releases their souls, which she collects. There is a final card to unlock that shows what happens when she gets all the souls.
do i need to die in this game? If no then why should i be punished (die) to do best possible action (see candle lady orgasm)?
Is there is a reason why this mechanic is inverted and not other way around, i.e. girl is normal at the start of the stage, get sad when on low health and horny and moaning when killing spirits/high on health bar
