New build w/colorblindness options

The latest build of Xtaloid now has command-line options to use an alternate color palette that may be more accessible to colorblind players. Please let me know how effective it is for you if you have red/green color blindness.

Use the following command to launch the game with an alternate color palette:  xtaloid.exe . --cblind  (Note the dot; this is important)

Other changes in this build: a couple of new levels, various bugfixes (e.g., pausing and resuming audio when pausing and resuming the game)
