I have a very simple question. When starting the new game it is said that if you select the story mode you'll be able to switch to the challange mode any time. Now when I'm playing in the story mode I cannot find these settings that would allow me to increase the difficulty. So is it actually possible to switch to the challange mode within the current game or do you have to start another new game to play with the challenge mode?
Thanks, I will appreciate any advice.
