Just another note here. 
 
Having played and enjoyed the game I felt that it was trying to show different ways of approaching various puzzles. 
 
Simple example (with some small SPOILER in it but I think this thread is way past that now) you have a Key and a Magic Key and you are faced by a Door and a Magic Door. Habit and Order dictates that the Magic Key go with the Magic Door but in order to solve the puzzle you must change your approach and abandon old habits. 
 
However upon completion of the game it is revealed that in simple terms You / Tim are the 'badguy' and in your quest to solve the puzzle you have brought about distress to others. 
 
Personally the revelation that you are the antagonist, combined with the feeling that the game had challenged me to think in new directions, carried another message: 
 
'Just because there is a puzzle to be solved it doesnt mean it SHOULD be solved.' 
 
Does anyone else wish that the Princess had just been waiting in the first castle for Tim in a very real and non explodey sense so we could have a happy ending? :D
