Looks really bad graphics wise...but i guess ill try it. I really like tower defenses but the last one I can think of that I enjoyed was defenders quest.
the regular defense grid is AS good as defenders quest.... This new one is in Beta.. Graphics suck as of beta, I know
I don't see anything super new about the genre.. they did add this multi level thing.. where new portions of the level opens up mid game.. but I find that confusing.. and unnecessary..
