Just a random idea for word search puzzles, I think it would be nice if we had the option to make "sudden death" style puzzles, where if you highlight the wrong letters / cells in the grid the puzzle will end instantly.
This could be used to prevent random guessing / exhaustive searching on puzzles without a word list.
What do we think?

And the mobile point from Rocket above is an important one.
