5 stars: A wonderful and addicting game for people that like the big grind. This game is very smooth and dynamic. It requires a good amount of thinking in the later levels and strageties will always be different with each on-going level, but it won't throw everything at you on the first stage. One of the only tower defense games that I have over 100+ hours on, if not, the only game. Truly a mobile game masterpiece.
