Some things I liked about the vocabulary game suggested to me:
- The timer that would count down to see how many words you can get in a certain amount of time
- There is a penalty when you get an answer wrong but the game does not stop when you get lower than zero
- You gain more points for getting a word right than you lose for getting one wrong
- The variety of different categories so you can’t get bored.
Some ideas for the vocabulary game:
- A similar timer to the one in this game
- A choice for hints which are separate from the parts of speech
- When a word is correct a popup shows all of the parts of speech of the word
