This is definitively one of the better Tower Defense kind of Games,
especially if you like me a fan of the "Lord of the Rings" Movies.
The Gameplay is very well balanced (More strategy rather then action) and the pace of the game is exactly how i like it. The only weakness for me is that the game is running a bit slow (even on my iPad2), so the UI handling is a bit slow and not so smooth. Also very convincing for me was that the first 3 levels were (and still are I suppose) free, so could test play them.
