Thanks your the review! It is actually intended for you to be able to do stuff like kill yourself or tell your party members to attack each other. When you leave a battle your party members can comment on what you did, calling you a fool or a madman and so on or even straight out refuse to listen to your commands anymore (you cant manually tell them to attack anymore and they instead choose their targets themselves) after telling them to attack each other for example, which is where the mind control comes into play.
As you correctly discerned though time was a major problem. Should've kept the scope much smaller after all!
