Changes since 0.1:

General:

	-  Moved the original chamber 2 to chamber 4, to provide a better
	   increase in difficulty level.

	-  Added a new test chamber to replace chamber 2.
	   This chamber also introduces the Aperture Science Non-Thermal
	   Non-Discouragement beam :)
	   
	     (As this is probably the most complicated thing I have ever made,
	     it may behave flaky in some situations. Please let me know how it
	     works (or doesn't) on your PC; if you can't finish the map because
	     of a bug, feel free to skip ahead :)

	-  Abandoned (for the time being anyway) the Nullsoft installer format,
	   as it may be a problem for Mac players, and users may be concerned
	   about viruses.


Chamber 1:

	-  added an extra obstacle to the second round;
	-  changed the two-button door mechanism to make it more obvious.

Chamber 3:

	-  minor tweaks only (clip brushes; missing textures, texture alignment
	   etc.)

Chamber 4:

	-  fixed shortcuts in the first section;
	-  added more indicators to help players understand the puzzles.
