My intention is to have other more subtle indications of when a ! statement is truly a lie and when it's just an emotional response. For example, you may not have noticed, but even in this demo Gema always shows a blank face when she's actually lying, but will be emoting if it's not an actual lie. I also want to encourage the player to make sure that they have other evidence that something a character is saying is a lie before they jump on it. Creating a system to achieve that is gonna be my main focus programming-wise for a while.
And twitter DM's could work, so that we don't take up too much room in the thread. My personal twitter is @brenna_asplund and the game's twitter is @void_talk. I'd be fine with you contacting me on either account.
