I hope there are a lot of improvements on the way, because as of right now this is at best a very middle of the road TD even if they levels were finished and the discriptions entered.
Exactly what I expect in a flash game, easy to learn, fast to play, not too hard. Great time waster. Good mute button and easy pause help a lot too. It's not a great game on a all games level, but as a flash game it's a success
