You can initially teleport 3 places in-game:
1) your current out-of-game physical location
2) the town center of your nearest town
3) random places of unclaimed territory
So I was initially teleported with my pet dog to an unclaimed area of central Missouri and I now claim vast amounts of territory near Waverly, MO (real world population 800).
So the real world map and territory claiming features make it fun, and its fun to be able to play on the phone when you're somewhere and need to kill time by killing giant spiders. Graphics are very basic 2d, but that doesn't make a difference to me when the game is fun enough.
If you want to play, then the sign up process allows you specify a referral code to get extra gold. I know that all referral codes give the same amount, 1000 gold. So please sign up with my referral code with this referral code, then I get extra food. My Parallel Kingdom referral code is: zldjcy
