I love tower defense games and this one does not disappoint. I would highly recommend.

I love this game. But since the update a couple days ago, the game will crash at the same spot every single time! Wastelands, level 1, at the 4th wave. Please help me!

Good game but here are some issues. 1. Some levels are too short; you spend your time developing a good defense and the round is over. 2. Some levels are ridiculously hard, especially early in the round. 3. Wastelands level CRASHES after the 2nd round. Please fix.

I really like this game and have played many of this genre. Been a little buggy for a while, but now, suddenly won't open. PLEASE fix this Dev's then 5 stars no prob!

I am a big fan of tower D games and this one is one of the better ones out there. It would have enhanced the game play if the levels were longer, but overall I'm enjoying the game.
