Nice concept but the obvious has already been stated. Bottom camping keeps you away from the stick men, make a way to lead the missles back to other targets and let the stick army be able to hurt itself (tank rounds hitting airplanes).
Good start but not very interesting after lvl 10 or so. Very repetitive. Options will let you auto release soldiers but its still too much of the same after a few levels.
Would it be racist if it was a black ball (or tank thing) smashing (or shooting) white balls (or growing white blobs)? Get a life and stop MAKING problems!!
low angle, full power - where the tree meets the green groun and where the green ground meets the sky. almost always 1st shot hits. But the exploding turtles are unlimited while our bombs are not making the last level almost impossible
