I paid $8 for it during the CC sale, but I really don't like it.
It's nothing like the original. Each level consists of an overworld with a boss character walking around, and a number of holes that you can go into for traditional Dig Dug action. There are stakes scattered all over the overworld, and the objective is to dig out the earth underneath the stakes, and when they're staked in all the way, a crack will form in the overworld. By doing this, you can make portions of the overworld fall into the sea (they're islands), hopefully taking the boss with it.
Yeah, I didn't really like that.
