Function module: Program Design:
1. You can select the game time to display the countdown. 1. Define global variables.
2. The number of English letters can be selected. 2. Control the game time function.
3. Statistical score 3. animation effect
4. Menu Options 4. Set the time when the letter image appears
5. Judgment Functions
6. game menu
7. Game time options
8. Display game time
9. game difficulty options
10. Game score
  
First: (PS: the artist is a hard injury)

Conclusion: The code is not optimized due to a long interval, and the occurrence interval of letters is too long. If you are interested, try to fix the issue. The code is for reference only.
