You will implement your Simple Tetris game by working through exercises 220 through 223. You will have the opportunity to customize your game, as you like, but these exercises provide a basic framework for implementing your game.

Be sure to follow the Design Recipe for each function you develop.

I've given you a head-start and completed exercise 220 for you. Read through tetris-220.rkt, run it, and be sure you understand the code (all steps of the Design Recipe for each function) before attempting exercise 221. Each exercise will be completed in the corresponding .rkt file, with the code from the previous exercise as the starting point.

Credit will be awarded based on:

• how completely you implement your game as specified by exercises 220 through 223,
• any personal touches you add to your game to express your creativity, and
• how closely you follow each step of the design recipe for the functions you write to implement your Tetris game.
  
  

• From your browser on the GitHub page for your Assignment 5 repository, click on the [Add file] drop-down button and select “Upload files”
• From your assign5 folder on your desktop, click and drag all four tetris-22*.rkt files onto your browser where it says, “Drag files here to add them to your repository”
  • just below the region of the webpage you should see all four files appear; they'll be just above the Commit Changes section of the page.
• You are now ready to commit changes! Click on the green [Commit changes] button.
• Your updated assign5.rkt file file should now be in your Assignment 5 GitHub repository.
