New, Improved, and Funner than ever
So far this game is the best a biggest of All the Bloons Tower defense game and includes a wide variety of new "towers" (As a few of them are mobile and air based) and if you are able to pay for the extra levels from the pay sight that should be attached to this game I would Suggest you get a few more of the extra tracks, their difficulty and fun far outshine any of the free ones given, though I also suggest (though it may seem tantalizing to do so) do NOT buy the instant level as having to deal with leveling up your account on this game just makes it just that much more fun and separates it FAAAR form any of the other Bloons Defense Game
