Dig a little deeper

Your robot digger needs to go deeper to hide from whatever horrors come from above. You've got to do the programming - keep it fed with instructions or it'll halt
and cost you valuable time. Oh, and you might as well make some money while you're at it, by grabbing gemstones on the way.

With life intervening, I didn't have time to add sound effects and music (yet), and the graphics are ... well programmer graphics. Still, hope you enjoy the game!
