I don't know why yopu think it's a good idea to put up your first flash game on kongregate. This isn't good, and it isn't impressive. I could make this in game maker in less than an hour.
I didn't really find it that fun... I just kept going until it wasn't possible for me to fire fast enough to keep away that stuff. Also, I didn't like the music.
I tend to dislike it when games increase difficulty by making you (your units) weaker than the opponents. In a game like this, I don't want to be mathematically trying to figure out how many units I need to field on my side when "the same amount as he has" should be enough.
