If you are still updating this game, I think a very convenient UI change would be so that if the letter/space is in the right position and the right letter/space it would be green, if the letter/space is right but not in the right position it should be yellow, and if the letter/space is not included it should be red (i.e. there are 4 spaces in "ALL YOU NEED IS LOVE" and if there's an extra it would be red or if there was an extra letter that's in the phrase but was already typed then it would be red as well). this would be amazing if this happened and would make the game more exciting
