28 | ||
29 | ;; The aim of 5x5 is to fill in all the squares. If you need any more of an | |
30 | ;; explanation you probably shouldn't play the game. | |
31 | ||
32 | ;;; TODO: | |
33 | ||
34 | ;; o The code for updating the grid needs to be re-done. At the moment it | |
35 | ;; simply re-draws the grid every time a move is made. | |
36 | ;; | |
36dfd590 | 37 | ;; o Look into tarting up the display with colour. gamegrid.el looks |
116f0564 KH |
38 | ;; interesting, perhaps that is the way to go? |
