If I remember correctly, there's some problem with the way it's coded that makes it impossible to add whatever code Kongregate needs to add badges. What a shame.
The challenge isn't counting my kills any more. I've got over 300 kills, but no card. That was the only reason to play this stupid game in the first place.
