Fun puzzles

Could use some UI improvements. Really could use a setting to turn off highlighting wrong letters so it doesn’t give away answers.

Also, sometimes puzzles aren’t well generated—the first puzzle I did, my last box to solve was an intersection of a wildcard and a character class matcher. Having to find the answer by trial and error isn’t fun.
