  29 ;; Bubbles is a puzzle game.  Its goal is to remove as many bubbles as
  30 ;; possible in as few moves as possible.
  31
  32 ;; Bubbles is an implementation of the "Same Game", similar to "Same
  33 ;; GNOME" and many others, see <http://en.wikipedia.org/wiki/SameGame>.

  67 ;;     - Customization: grid size, colors, chars, shift mode.
  68 ;;     - More keybindings.
  69 ;;     - Changed shift direction from to-right to to-left.
  70 ;;     - Bugfixes: Don't remove single-bubble regions;
  71 ;;                 Animation glitches fixed.
  72 ;;     Tested with GNU Emacs 22.0.93 and 21.4.1.
