Thank you sir.

I have another general piece of advice - avoid flamethrowers like the plague, they're terrible. Short range, they actually make the ants go faster (stupid idea), and they seem to counter the effects of the ice cannons on top of it so you can't even get any use out of the most useful weapon in the game. The only good thing about flamethrowers is the high damage, but it doesn't really matter once you get to a high level anyway.
