I am a princess.
The second game starts when you have cleared the normal game and witnessed the end of it.
The first game has a blue border and the second game is red.
Beginning on the back side of the tower, you have to continue with the same power you had on the normal side.
Your gold is confiscated.
(So, you had better offer gold at an alter before winning the game.)

But the back side isn't so tough...
It's actually easy if you strengthen the brave-man in the normal side.
In other words, Before you go to the back of the tower, increase your level on the normal side.

Also, the fairies don't appear at the back side.
