Could someone clarify three things for me?
I thought when I earned my first crystal that, with each subsequent one, your energy level increased; i.e., instead of 100, it went to 103. Although I've since earned five more crystals, that level has not changed.
I assumed that, in order to earn a completed crystal for a region, one had to earn more stars, especially in "shadow mode", but whilst I was working on Rio, my NY crystal magically completed itself! Why?
Finally, does every region have a crystal? I've found two just by tapping around, but the location wasn't obvious.
I appreciate any information
