Leading Assumptions and App Design Details

• App Design
  • The game board is designed with a size of 100x100 cells.
  • Game will start when user press SPACEBAR
• Score
  • The game starts with a score = 0 and will increase by 1 every time you eat an apple
  • When the program is first run, the highscore will be = 0
  • High score will be saved when snake has been played to death (game over)
  • The program will store the 10 highest highscores
  • Highscore will not disappear even if the application is closed
  • Score will be saved in highscore.dat
• Snake
  • The initial length of the snake before it starts = 5 cells and will increase by 1 cell every time it eats an apple
  • The snake will die when it hits the wall or hits the body
  • Boostspeed when pressing SHIFT on the keyboard
  • Every time the score reaches a multiple of 5, the snake moves faster
  • Boostspeed adjusts the speed of the snake
• Apple
  • Apples will appear randomly when the game starts
  • Apple size 1 cell

UI

1. Before the game starts

2. After the game ends
