My Favorite!

I love tower defence games and puzzle games. This one is both. Tons of fun trying to figure out how to use limited towers to get 3 stars on a level. One tip is to focus on removing all
obstacles, you get 45 gems even if you have done it on that level already and its helped me get 3 stars on levels I was stuck on.
