26 | ;;; Commentary: | |
27 | ||
28 | ;; The aim of 5x5 is to fill in all the squares. If you need any more of an | |
29 | ;; explanation you probably shouldn't play the game. | |
30 | ||
31 | ;;; TODO: | |
32 | ||
33 | ;; o The code for updating the grid needs to be re-done. At the moment it | |
34 | ;; simply re-draws the grid every time a move is made. | |
35 | ;; | |
6772c8e1 | 36 | ;; o Look into tarting up the display with color. gamegrid.el looks |
116f0564 KH |
37 | ;; interesting, perhaps that is the way to go? |
38 | ||
39 | ;;; Thanks: | |
