W,A,S,D and Arrow Pad: The up arrow initiates forward momentum. After that, you will have to use left, right, and down in order to control the direction of your worm.
Satisfy your craving! You hunger and when you hunger you must feast! Worm your way through distant earth, follow the footsteps of the humans above, and track down your next meal. Consume chickens, and people, and livestock like cows and goats. You may even jump high enough in the sky to eat a spare bird or two. Underground there are also all kinds of lizard creatures you can feast on but it will never be enough. As your hunger is satiated you will begin to grow bigger and as you grow bigger you will become more hungry. Soon, the militaries of the surface dwellers will be alerted to your presence and by then you'll be forced to not only feast upon humans but also go into direct combat with them.
