WormAndBird (Nokia 3310 Jam)

Use WASD to move and space to either attack as a bird or to dig as a worm. As a worm, you earn points by exploring new areas, and as a bird you gain points by killing worms. When you succeed as a bird, you give your worm more health, and when you succeed as a worm, you give your bird more time to kill. You have a limited amount of time when you play as a bird; after a certain amount of time, you run out of energy. The bird can also die by running into the top of a tree. A worm can die by being eaten by a bird.
