managed to get all the way to the last checkpoint of the last level without using up any ants. i can't seem to abuse the slope enough to get to the end but i bet its possible to do it if you are frame and pixel perfect.
I don't know, I thought it wasn't possible on the first and second level either and yet some did it ^^
all three levels can be done without any ants on counter. see my comment it has youtube video
