Word puzzles? Without score/time pressure? I am so in.
There seems to be a small (non-breaking) bug where the letters don't quite clear if you switch levels. After finishing the warmups, I clicked on the "1" (not realizing it was taking me back to what I had finished), clicked "SA", realized my mistake, hit "home", and went to the first level of the next set. When I did, the "SA" were still there, and I ended up spelling "SAMYTH". (Which the game accepted as "MYTH", so as I said, non-breaking.)
OK, back to the game. Loving it so far. :-)
