Being able to change the letters is a cool twist!
But what I meant about continual play, is that you have to use your same clue-words to figure out the new word. So you'd have to balance using clue-words that will help you determine your current word, versus clue-words that will help you solve *any* word. It's nice that hellowordl allows you to keep playing more easily, but it wasn't quite what I was hoping for. Such a great name, though.
