The Word Alone
Alone. A word that has both good and bad connotations. For Matt Rix (Trainyard) and his Ludum Dare entry, it's a goal. In The Word Alone, you are given a Boggle-esque board where you are tasked to eliminate all the other letters to leave just 'A', 'L', 'O', 'N' and 'E'.
Letters are moved off the board by first typing a word using the letters available to you on the 5 x 5 grid (unlike Boggle, the letters do not have to be adjacent). With the [arrow] keys, your chosen letters then move in unison, and any unlucky letters on the edges are nudged off and out of the game, sumo wrestling style, just without all the action. All letters are subject to these actions, so it's up to you to keep an eye on your five golden letters and make sure they're the last ones standing. See if you have the word and spatial genius to accomplish this.
