He worked on the Namco Galaga board.

Dig Dug was developed by Shawichi Fukatani, who worked on many early Namco arcade games, and was developed by younger colleagues of Galaga creator Shigeru Yokoyama. 

The music was written by Yuriko Keino and was the first game she worked on for Namco - a short jingle made when the character was moving was created when the leaders wanted the game to be the sound of walking. 

Namco called it a "strategic digging game" because of the large number of strategies used to defeat enemies that were actively used in the marketing of the game.

After the release of Dig Dug was well received by critics for its exciting gameplay, cute characters, and strategy, and was a popular game in the golden age of arcade video games. 

It has been met with a long series of sequels and spin-offs for several platforms, along with ports for home consoles and digital showcases. 

Dig Dug is also included in many Namco video game compilations for several systems. 

Characters from the game appear throughout the Mr. Driller series, based on the dig Dug gameplay.

Dig Dug is a labyrinthine video game. 

Controlling the title character, the player must destroy enemies on each screen; 

These are puki, creatures similar to red tomatoes, with comically large glasses, and Figaro, green dragons that can breathe fire. 

Dig Dug can defeat these enemies by using a bicycle pump to inflate them with air until they explode, or by crushing them with large falling stones. 

Bonus points are awarded for crushing multiple enemies with one stone, and dropping two stones in the stage will cause a bonus item to appear in the center of the screen, which can be eaten for points. 

Once all enemies are defeated, Dig Dug will move on to the next stage.

Enemies can travel on solid ground to reach the player, where only their eyes will be shown. 

Inflated enemies do not pose a threat to the player, allowing Dig Dug to pass through them without harm. 

The game will play a short jingle when Dig Dug moves, stopping abruptly when it's inactive. 

If the player takes too long to clear the scene, the enemies will become faster and more aggressive, which will indicate a short ringing. 

The steps are marked by the number of colors placed at the top of the screen. 

In later stages, the color of the mud changes, and the speed of movement of enemies increases.
