No, imo that won't be okay. Competition is not in a picture if one can't even finish a round :)
Perhaps you can have competitive and casual modes? One with the score and no undo, another without and with respectively.

There could be an official word each day that is ranked, but also randomly generated puzzles that you could play limitlessly. Only issue there is when you have words appearing in the casual mode and ranked mode, which I'm not entirely sure how to fix.
