New area has several store rooms. One on the same level.

Preliminary. And a bit different. Not shown, ice down below, not water.

821 x 1000 pixels so no larger in gallery.

There are two places where the cutaway walls don't quite match. An adventurer could toss a burning torch down there, to see what is below.

Uploaded a numbered map, and added arrows where the break in the walls are located.

I had meant to have one huge floor, with stairs going down in several places. I may put that on the right side of the map.

Note the name change to Not The Twin.

I've come up with I think a completely different iso dungeon setup. I'll start a new thread for it.

Starting at the top and 'back ' is the best way.

Placing a floor piece at the bottom on a stairs is something you have to learn. Back then to the 'front ' of the stairs.

Mostly I had to experiment.

Windows did a number on various software help files by not keeping them up to date.

We are rather helpful. And there are videos on YouTube as well.
