Sarah Northway's Word Up Dog features a cute little dog that has been swallowed up by the earth. It's up to the player to guide him out by tunneling through randomly generated levels, picking up letters, and forming words in order to earn bones. Bones can be spent to advance to the next level, or purchase powerups. Dig wisely, though, as every square you tunnel through costs you bones! Players can choose between Hip Hop English (allowing some slang and proper nouns), Queen's English, French and German.
