I loved this, played as all the starting locations. Beating the game as center was a neat little puzzle.

Perfect in it's simplicity and ease of play.

I feel like this is ripe for a sequel with more economy options (choose if territory specializes in defense, manpower, or cash)

Potential improvements, in order of priority:

1.  Make "Tutorial" screen visible during game-play.
2.  Mention that you can consolidate any/all of your armies to any/all of your territories
3.  Ability to choose starting location (from presets)
4.  Ability to choose color
5.  Option to continue playing after game completion
