180,603,968,395 and the game got laggy so I gave up... well I'm not too sure about the last number.. it's cut off.. either way.. not too shabby.. I like this one better than the first Effing Worms game.
88,713,019,882 and still going... I've gotten to the point where my worm is bigger than the screen.. the only bad part is you can't upgrade your size or speed unless your out of the ground so I can't just press up and watch T.V. or something... bummer.
