My only gripe is that since the pieces the tank shoots are considered two individual balls, they don't behave like Dr.Mario's pills.
This makes the game more limited in how you can approach the alien onslaught by making it much easier to kill the aliens using columns of spheres than by using rows, and limits combos. (Even with the addition of ceilings and foes in later levels)
