I agree with HezbollahFantic, it's crap, but I also agree with Senekis93. It is unbalanced and the graphics need cleaning up. I would suggest you keep working on it and do the 1.0 to 2.0 thing. It does have potential.
I have play pretty much every tower defense game on Kongregate and this is one of the few that has kept my interest. Thanks for updating and keeping it interesting and fun.
