I forgot how I landed on this website of a classic PC game: Digger. This game —as I remember— is as famous as PacMan. And the gameplay is not too much different either. I used to love both games and could play them for hours straight a day, before mom came and mad at me. What an old happy days! 
For the sake of nostalgia, is there somebody interested to convert the game to Codea? All the required resources are available on the website. The source code, graphics and images, documentation, etc. is all there. @ruilov maybe?
