;;; Commentary:
;; Bubbles is a puzzle game. Its goal is to remove as many bubbles as
;; possible in as few moves as possible.
;; Bubbles is an implementation of the "Same Game", similar to "Same
;; GNOME" and many others, see <http://en.wikipedia.org/wiki/SameGame>.
;; Installation
;; ------------
;; Add the following lines to your Emacs startup file (`~/.emacs').
;; (add-to-list 'load-path "/path/to/bubbles/")
;; (autoload 'bubbles "bubbles" "Play Bubbles" t)
;; ======================================================================
;;; History:
;; 0.5 (2007-09-14)
;; - Minor bugfixes.
;; 0.4 (2007-08-27)
;; - Allow for undoing last move.
;; - Bonus for removing all bubbles.
;; - Speed improvements.
;; - Animation enhancements.
;; - Added `bubbles-mode-hook'.
;; - Fixes: Don't move point.
;; - New URL.
;; 0.3 (2007-03-11)
;; - Renamed shift modes and thus names of score files. All
;; highscores are lost, unless you rename the score files from
;; bubbles-shift-... to bubbles-...!

;; Disable menus and counter when game is over.
;; Tested with GNU Emacs 22.0.93
;; 0.2 (2007-02-24)
;; - Introduced game themes.
;; - Introduced graphics themes (changeable while playing).
;; - Added menu.
;; - Customization: grid size, colors, chars, shift mode.
;; - More keybindings.
;; - Changed shift direction from to-right to to-left.
;; - Bugfixes: Don't remove single-bubble regions;
;; Animation glitches fixed.
