I think you should change the game back to the first type, with tons of waves, so we can actually get the badges and skill points. Or increase the money the monsters give. Or increase the number of lives we start out with.
Most of my army was composed of battleships(for turrets) and raptors(for everything else) at the end. Throw in a few commandos and the guys at the end would have been easier than the level itself.
