Didn't really have to upgrade health and never used a bomb. Also the toggle button for the sound only turns it off and not back on.
It gets really boring after a while
It was short and easy. You didnt eve have enough levels or enemy clocks to pay out enough cash to full upgrade everything.
fun but kinda to easy i didnt loose any life at all
Way Too Easy
It's a pretty well-made game. Trouble is, after wave 12 or 13 it becomes way too easy. The number of attacking enemies dropped down dramatically.
