Very original and innovative. GOTY 2012? People are voting like crazy on Steam Greenlight. http://steamcommunity.com/sharedfiles/filedetails/?id=92916134&searchtext=
Remember that there are still people who have (Gasp!) not played DoD at all and have no idea what a Diggle is. This was probably an attempt to make a shoddy clone of Terraria. But once mostly finished, the name stuck. If anyone seriously thinks the courts should handle this and sue the pants right off this person, remember that he doubtlessly wanted to make a game, and the name is fitting for a digging game. That is as far as it went. And that is as far as it should go. Live and let live. (Until they least expect it. Then they wake up to The Bolt Council...)
Still surprised it hasn't been taken down. Even if not legally objectionable it kinda goes against the spirit of the system.
Then again, the title is probably more... inspired by a 2001 game called Diggles: The Myth Of Fenris. It's like the developers played Dwarf Fortress and went back in time to make it graphically accessible! By the way, Fenris is Odin's lapdog...
Oh yeah, Wiggles. That's one hell of a fun game. Shame my copy doesn't want to work anymore and I'm too lazy to look for the backup CD, though.
