Hi Richard,

thank you for your feedback! We'll try to put directional walls in the next release!
Hello,

thank you for the report. This bug has been confirmed and will be fixed in the next release.
Sorry for not answering earlier, but holidays came up.

The stairs between two floors always belong to the floor below. You can check that it works if you use the Generator Debugger (Window drop down menu -> Generator Debugger), select your dungeon and click on any "Select Storey X" button.
Note that the bottom floor is always labeled 0, so if you have 4 floors, they will correspond to zones 0,1,2 and 3.
So, if you do GetObjectsOfZone(0) you should get the ladders between floor 0 and 1.

I hope this can clarify it fot you!

Not yet; right now it will put the entrance on the bottom floor and the exit on the top floor. In next version you will be able to specify where you want to generate them.
We will add this feature in the next version.

The building's top floor already got a ceiling; maybe you're looking at it from outside, so the ceiling's normals are pointing downwards.
All the generated stuff is parented to one single GameObject, so you can simply scale that.
You can use your own graphic assets for ladders/stairs. Just have a look at the example graphics for the Fantasy dungeon example and follow those as a guideline to create your own.
