Shadow Codex is now available for sale for $4.99.  Think of it like Puzzle Quest, but with a word game mechanic instead of match-3.  This video shows the first 10 minutes or so of gameplay, including the tutorial.

Master words, spells, weapons & equipment to defeat over 45 characters and monsters.

There are also 3 mini-games to add some variety to the quests:  Endurance Trials are like a timed mode, Collection Challenges are a race to collect items on the word game board, and Chest Unlocks are like a word-search game that can unlock a chest for some goodies.
