Good, simple fun with a terrible difficulty curve

Ive played many tower defense games in my time and Little Commander is certainly in the good and great category, however there is a rather large difficulty curve that appears in the 3rd level of the game. Once you get to get to level 3 get used to the first two levels. You will be playing them over and over again just to get the upgrade points so you can attempt level 3 which gets quite hard very fast. I remember playing this game before and getting so bored with the first two levels that I just gave up and bought more update points.
