Making a hallway of non Euclidean portals

The original Doom levels were built with rather simple geometry, making them a great testbed for various advanced features. Things like mirror reflections and nonEuclidean portals are pretty straightforward to make in Brahma Engine, as these features are native to its map format. Connecting remote locations takes no effort from the mapper and is accessible with a single keystroke. Of course, there are certain caveats and workinprogress functionality that is planned to be supported. For example, connecting walls to floors, ceilings and vice versa is provided by my map format, but has no support by the current renderer. Brahma Engine public demo download:
