OK game. I don't understand the point of having more than one level on this however. They're all the same. Nothing in this game makes it different from any other TD game out there. No cash bonuses, no upgrading of towers, no skill points, nothing. as soon as you got the towers in place and are ready for some hard waves, the level is over.
