Use the arrow keys to move the black ant. The black ant must eat all the sugar cubes before the red ant catches it. The black ant gets fatter, and easier to catch, the more sugar cubes it eats.
Getting the ants legs to move in a believable manner was quite tricky; I'm not sure I got it entirely right, but this short animation by Ryan Marzolph certainly helped me to visualize it http://youtu.be/p7siGiRTvXw
