Great App, has potential. – Crossword (US English) Review

I really enjoy the app, however, I'm hesitant to purchase more puzzles until certain "tweaks" are done. It needs to include hints and/or show errors. Also, I believe I completed 3 of my puzzles with no errors, but I can't tell! Please fix and I'll give 5 stars.
