Excellent details
I was shocked to hear such good voice acting from the tutorial, and the sounds in general are tip top, the graphics are quite decent, this is definately the most flashy TD game I've seen in a while, however there was no pioneering as far as the TD games go, and the gameplay is not very refreshing to say the least.
You had a really nice chance of making a bold change to the gameplay, but in the end, this was safely inside the typical generic TD game.
