Updates:

• Now you can play "Code World" with any keyboard layout
  
• When you copy some text in the game's code editor (Ctrl + C, Ctrl + X), it goes to the OS clipboard. Also you can copy some text anywhere outside the game and paste it (Ctrl + V) in code editor of the game.
  
• File "list_of_functions.txt" contains the "help" section content. You can find this file in the root folder of the game and even print it if you want.

If something in the game doesn't work properly on your PC, please tell me in the discussions!
