Very good defense game.
The game was very well put together. The steady upgrade of the ages made the game more entertaining and kept it together with a nice fresh look each age without taking away from the game play. As for me when I made it to the last level I found it to be a constant match back and forth until finally I managed to conquer, however I enjoyed every single moment of it and this game keeps you entertained till the very end. Over-all great game, good fresh look, and very entertaining game play.
