Ants of Unusual Shape

Try to have your ant colony survive as long as possible! Your ants will bring back food to the colony, spawning more ants! But beware of food that stay for too long... Something hostile make come for it. Your ant genome will mutate based on the ants that brings back food, but you can help it move in the right direction with your powers as colony leader, and increase the speed or the life expectancy of your ants. Or you can just spawn more ants when in dire need of more population...
