Dig Dug for NES

EditBy: The objective of Dig Dug is to eliminate underground-dwelling monsters. This can be done by inflating them until they pop or by dropping rocks on them. There are two kinds of enemies in the game: Pookas, round red monsters (said to be modeled after tomatoes) who wear yellow goggles, and Fygars, green Dragons who can breathe fire. The player`s character is Dig Dug, dressed in white and blue, and able to dig tunnels. Dig Dug is killed if he is caught by either Pooka or Fygar, burned by a Fygar`s fire, or crushed by a rock.It takes four `pumps` with the player`s action button to inflate a Monster until it bursts. If left partially inflated, the monster will deflate and recover after a few seconds, but half-inflating is a useful way to stun an enemy for a few moments, especially to make sure it remains in the path of a falling rock. You can also pass through the enemy while he is deflating.The monsters normally crawl through the tunnels in the dirt but they can turn into ghosty-eyes and travel slowly through the dirt.More points are awarded for eliminating an enemy further down in the dirt (the levels are color coded), and the Fygar is worth more points if it is inflated horizontally rather than vertically (because it only breathes fire horizontally). More points are also awarded for dropping rocks on enemies in order to eliminate them rather than inflating them. If one enemy is killed by the rock, it is worth 1000 points. The next two add 1500 points each and any after that they add 2000. The act of digging is itself worth points, giving ten points for each block dug, so some players do as much of it as possible in situations where the threat from the remaining monsters is minimal.After the player drops two rocks, Fruits and vegetables (and other edible bonus items, such as GALAXIAN flagships) appear in the center of the playfield, and can be collected for points if the player is able to reach them before they disappear.
