These shots are kinda fun as well. I cleared dungeon level 10 on nightmare completely, and then moved on to 11. It turned out to be that level 11 looked exactly the same as 10. (Kinda weird since all levels should look different.) The monsters in the two levels were different, and a few chest were positioned elsewhere. But that's all that's different. Take a look at the shots and compare them.
Just the monsters and a few chests indicated that the levels were different.
