Bloons tower defense 4

bloons tower defense 4 is kind of a remake of BTD3 but you have ranks and the higher rank you have the more stuff you get. When you get all the upgrades for one thing you will notice it will say "can't upgrade until you get to this rank" because the more bloons you pop the higher rank you will get and you get more 4th upgrades. Also there are banana farms and you will get more money after each round.(get them in the beginning so you can get more money) there are also ring of fire, sun gods, lightsabre throwers etc.)
