From Adam Parrish:
Word game meets platformer in Lexcavator, the hybrid action/puzzle game. Your goal: Guide @ as deep as you can into an infinite well of letters by clearing words from the board. Don't have every obscure three-letter word memorized? No problem, Lexcavator's fluid level generation algorithm keeps the board filled with longer, more satisfying words. Power-ups (like * Blast, ? Alchemize, and _ Erode) can help or hinder your progress. Use them strategically.
