A goo game although there no penalty for placing towers, it does not cost a thing. So I felt that it was kind of easy.

Good, except level 19 is impossible.. lol , you forgot to upgrade reload time for buildings constructions, and let people level to 4 or 5...
Enjoyable game with nice graphics. In later waves, however, I felt it was going out of control - the main gun was too weak and ran out of power too quickly, and I was deploying towers and mines pretty much at random whenever I could.
I hate how we have to rebuild all our structures at the beginning of each round.
Might not bother finishing this.
Two words is all, challenging and fun.
