Added some extra pillars.
Much work to improve the lighting contrasts in this map.
Moved half of the stage by 3 wall-units because the entrance door was moved by that much too.

Many improvements. The general solution remains the same.

Several small changes that should make previous unintended solutions no longer acceptable. It will also remove a few glitches, such as accidentally getting to push your cubes inside an observation room. See this video for more information: http://youtu.be/Y5uHVIV6b44

Added automatic savepoints.

One more change to seriously discourage leaving the cubes where you can't retrieve them later.

Cosmetic changes. Accidentally created uneven portalable surface patterns when moving rooms around.

Changed the geometry of the first ceiling room a bit in order to discourage a wrong solution that leads into becoming stuck later on.

Initial release.
