Aweome game

A lot better than 95 percent of the TD titles out there. Of dozens of TD games on my ipad I keep returning to the same 4.. And this is one of them.

They update very often (30 new maps since Ive started playing!) and have a nice upgrade system. Well worth the money. Very kingdom Rush-esque. S if you liked KR and want more, Id get this.
