Base placement

On the other note remember that if you dig too deep you'll free Balrog get to lvl that can be accessed from other mines

Can anyone confirm if and how that mechanic is implemented ? I mean if two mines are at lvl nine, do you have to dig all the way ( that you would normally walk on the surface ) from one to the other ? or ... ?

I heard last year that the underworld "deamworld" or whatever is as large as the above world.

And basically your mine entrance is mirrored on that underworld map.

Unsure how true this is.

EDIT: It was compaired to "The Nether" from minecraft, as the best way to describe it.

But the Nether is way smaller than the real world in Minecraft. It is parallel to it, but short distances travelled in the Nether translate to way longer distances in the real world.
