Um, I can't see any villagers ever on this game. I clicked checked where I would think they are and sometimes I pick one up, but otherwise they're invisible.
Hm, got way over 2K kills on medium, and still no badge. Weird. Otherwise Great game, great to satisfy while waiting for Gemcraft (and mourning for Mushroom Revolutions) ;)
