There is a doorway that is a different size when heading south versus heading north:
- Move north no echo
- Move south after heading north "You strain a bit and barely manage to fit through the door."

Issue being if you go into the room enlarged as a giant you cant walk back out.

Small log snippet below:

A Dark Passage
The southern end of the passage leads out of this dark and damp tunnel back
into the world. This close to the surface, the stench of mold is barely
present, but it wafts in from the darkness to the north. Damp earth forms the
walls, floor, and ceiling here but the structure looks strangely stable even
without any visible supports. It is possible to continue north into the
darkness or return to the outdoors in the south.

Earthen walls touch a dirt ceiling and a floor of hard packed mud. No light,
natural or otherwise, can be seen from here. It is cool and damp in this
tunnel and the heavy stench of mold hangs in the air. The passage takes a
bend here, curving to the south. A subtle breeze carries in from that way
and you can only assume that following the faint scent of fresh air will lead
you out of the darkness.

I fixed this previously, but may as well respond so its clear to anyone still worried about it.
