We had a huge response to the first game, most people seemed to have lots of fun despite the game being fairly easy by most td standards. We've added 3 new maps, one for three difficulty settings. We've also added a new tower type, the boomerang tower, as well as some new 'on track' items: Road spikes and Monkey glue. A sequel wouldn't be complete without more bloons of course, and we've added 2 nasty new types, the lead bloon and the rainbow bloon.
Enjoy.
