Big Bug is a game similar to "Dig Dug", in which you control an ant that must collect yellow seeds that have been taken from his anthill and buried deep in the ground. But beware of the beetles, big red ants, and worms that try to stop you. Fight off these nasty insects by shooting ant eggs at them. But if one hits you, you lose a life, and the game is over when you run out of lives.You get points for seeds and for wounding or killing the enemies. If you get enough points you can earn an extra life.Once you've collected all the yellow seeds you can continue to the next level. The first five levels are unique, but the next 11 levels are randomized, and the enemies get faster and faster. You win after you've completed all 16 levels.The game includes music and sound effects.
