Anteater

Anteater is a maze game released in 1982. The player controls an anteater who runs his proboscis through maze-like ant colonies eating ants and their larvae. The player can only eat ants with the tip of the anteater's proboscis. If an ant bites your proboscis at any other point on the tongue you lose a life. Pressing the second button will quickly retract the anteater's proboscis. You can also eat worms from behind, but not head-on; doing so will also cause you to lose a life. You must eat all ant larvae before the timer runs out, then you advance to the next stage. "Anteater" enjoyed a fair amount of success, being copied by many other companies; some notable "Anteater" clones include "Aardvaark" and "Oil's Well".
