Defense of towers and the hero

to strike a balance, if you can survive this game I can say surely that you are pro, because this map is the most harder that I know(more than Green Td- Green Td pro- Green Td circle- Green Td circle pro- and lot more).
Well. This map objetive is to survive all waves and survive against the monsters attacking the base, there are a lot of them, so don't think much and build or buy books for your hero, is a good idea
