This is a great concept, and it's fun to play, but it's also brutally difficult. I've had a couple games now where I match no words and just watch the blocks rise until I lose. 17 seconds is a pretty short time per row, it could really use a difficulty adjustment. Also, the letter distribution seems to favor rare letters more than it should, and it keeps serving me big chunks of the same letter over and over. Randomness plays a big part in how I do in a game, and that doesn't feel great. If these could just be tweaked, this would be an all timer that I would love to sink tons more hours into.
