It's a very good game, with nice looking levels and infinite posibilities thanks to the community levels.

The game is well made for both casual players and hardcore players, learning it isn't that hard but mastering it takes time, overall a great game and experience. You can play the game for hundreds or even thousands of hours and still have stuff to do, the overall replayability and amount of content in the game is insane, I definitely recommend it, especially if you enjoy tower defence games.
