Ant Tracks puts you in control of an army of ants on their way back
to the nest after a successful foraging.
Your job is to guide each ant to its proper food store depending on
what it is carrying. Food stores are the long narrow hollowed logs
and each is labeled with a picture of what should be deposited
inside: bug, grub or leaf. Ants move like Lemmings along the maze
of horizontal twigs until they arrive at a food store, at which
time they hop in regardless of whether it's the right one.
