Buzz Words - Learn to spell

My daughter loves to play this game, but there are a few issues that need tweaking. We'll keep the game in the hopes these issues get fixed: first, some of the words are not scrambled (e.g. Weasel), which makes it silly. Secondly, in the medium and long category, some of the words are too long to fit on the screen (and I'm using a regular sized iPad), making it very difficult to unscramble since you can't see all the letters at once. Thirdly, the length of the words seem random - when playing the medium length words, my daughter got dragonfly, which seems long, and bear, which is obviously short.
