Amazing idea and beautiful artwork!
But as far as I saw there is no way to reenter the AI Directions Menu if you input something wrong.
Or maybe I just missed it. Still, very good job!
There is a "change" button on the pause screen which will bring you back to the Directions Menu. Although if you are on the webplayer you need to hit P to pause, since ESC will just exit.
Ah, that makes sense. My bad :)
