Really liked this one, very neat puzzle game! I like how we never see the Wizard's original form... so he was created by the blue wizard guy (I forgot his name)?
I also liked the secret cheat codes! I even managed to guess 3 before... y'know. But...
spoiler territory below
...there's one more that you don't tell us about, and I guessed it! One thing I don't get though... what does the winner code do? Change the dialogue of everyone to the one that appears after you beat the blue wizard guy?
