Ravi: The problem was that I didn't have an alternative answer. All I knew was that say the third letter had to be a 'p' instead of a 'g'. So, I needed to actually erase the first answer. Because it wouldn't let me erase (as near as I could tell), instead, I had to put in X's for the letters I didn't know. This cluttered the puzzle, making it harder to see which words I still had to work on, and was a pain in terms of user experience. Maybe spaces would have worked, but that would still have been more effort that I wanted. None of this is a major deal. I'm just giving feedback.

Thanks,
