I get that you have to put the not dopler stuff in as they are sponsors, maybe turn the volume down a little on that? I typically don't play the games with sounds and as they remember it's great when I load them. Except your not dopler intro which almost blows out my speakers if I forget to mute it.
Without linking it to Facebook I would have made it a 5/5 for fun factor. Linking it to Facebook, which I don't use or like, gives it a 1/5 just for associating it with Facebook. This is Kongregate, not a meeting place for Facepalm.
Nice game, but maybe hard was a little too hard. I agree with the people talking about hitting gnats with a bb gun. I tried several combos of starting upgrades and nothing got me past part 2.
I have to agree with a lot of others. Great concept for the game but the enemies difficulty and the speed of the waves are too fast. Unless your commentary on politics is that obama can't succeed in which case I think I got that one.
