Dealing with the princess is as far as you can go in the current version of the game.
I just finished it, and I kinda wish that at the end it took you back to your roost as the game is unfinished, so we could still interact with our people. I get that we're supposed to explore all possible options, but with ten pages of saves, I'd like to be able to go back to my Spire and interact with my girls.
I can't wait for the next update. Such a good game.
