More feedback:

- I was intently staring at letters and didn't notice you get a definition as a hint! Maybe the hint UI needs a tweak.

- it needs to allow permutations that are also words, or at least provide an additional reward for finding those (maybe an extra half point).

- there should be a "clear" button next to shuffle.

- there should be a "pause" button which hides everything and stops the timer. My waitress came by as I was playing and I lost.
