Challenging, a little clunky

Solid, challenging game, forces you to think of lots of possible word combinations. Hints help you through when you cant visualize any word words or youve given up. Its a good brain stretcher, with three minor issues: 1-letter switching should be possible between any two spots not just in one row or column. 2-if you solve one of the words correctly, show it solved, maybe even auto-fill the duplicate word to eliminate busywork. 3-after using a hint, show that letter as solved. Fix those minor issues and youre 5 stars.
