It's interesting the variations in ratings. Personally, I think that coconut118 didn't play it long enough. Yes it is boring towards the beginning, but suspense builds.
I liked the entire game, but I feel there is one thing you really need to fix before it becomes a really good game:
Make the game more difficult, you tend to have small bursts, and even towards the end, you're still sending manageable numbers. I'd like to have seen an army of 20 SUPER tanks, at the very end, I want to have to USE those turrets. I personally beat the game on my first try (didn't die once).
P.S. You also need about 5 more levels.
