Really nice game, I loved the map system! One problem I see with the game is the lack of a 'very easy' mode. I'm an ... average typist, and I was struggling on easy. One thing I would recommend would be to add an expert difficulty, and shift each difficulty down one, i.e. hard is now expert, medium is now hard, and easy is now medium. Then you could add an easy mode, to create 4 difficulties. Easy afterwards would be more forgiving than easy right now.
