I don't know what to say... This is the most touching, amazing, game I've played in a long, long, time. I'm so glad that I rediscovered this game...
You have a real talent. And I mean that most sincerely. Keep up the fantastic work.
So... the prince got swapped into the body of the black wizard's apprentice, who swapped bodies with his master...
That means that the black wizard, disguised as the prince, was about to absolve the black wizard, who was really his apprentice, of all 'his' crimes. Then the prince, in the body of the wizard's apparentice, enters and reverses the spell. That works. Somehow.
