I absolutely love this, but I'm really struggling to get the True Ending. I feel like it has something to do with the number of runes the client in Session 4 decides to take -- he pauses before taking runes, as if I'm supposed to do something, but no matter what I press he only takes three. Additionally, there's an open slot for a fourth rune. And no matter what order I put the runes in, it's always the same divination.
I also can't figure out how to get the casualty rate above 2%. (I once got 0% but that wasn't the answer, so I'm guessing I have to go higher.)
Any tips would be appreciated. Thanks for making such an intriguing game!
