Of course! A Truth is just meant to be something fundamentally true about your character, something that-- if known, gives someone power over your character. It can be something like why you and your ex broke up, a small piece of childhood trauma, a fear or a hope or a dream. These are not decided beforehand, but are discovered through each scene as your characters talk. If someone feels that a Truth has been discovered, they posit it and if both players agree, the one who learned the Truth about the other gets a "point" so to speak.
But thank you for the feedback! I'll have to go back and make that more clear when I have the chance.
