Evaluation and Coding

I am currently writing my evaluation. A few things that I could change in my game are:
1. When the user clicks on a letter, that letter button disappears so that user cannot click on it again and throw out the counting of the letters.
2. This also benefits the user so they know what letters have been used.
3. The displaying of wrong letters beside the gallows would also show the letters that the user has used.
4. The category and difficulty choices that I originally planned would give the game more flexiability for different users.
5. A high score would have been a good addition as well.
