Intriguing and fun. I haven't played it enough to confidently suggest changes to the game mechanics, but I think they're strong enough on their own that any/all added UI comfort would be welcome - like others have been saying, a less clunky dictionary (maybe right-click on a word on the board to look it up?), and maybe a preview of whether your attack is going to succeed or not (maybe just on 'easier' levels, since there is an element of not making a 'simple' miscalculation while you overthink a complex board position, like in Chess. Also, think of a game like Puzzle Bobble / Bust-a-Move where the first few levels give you a line showing you exactly where your bubble is going to land).
