Snake in Console

My first program, I'll be very happy for any comments.

About the program

The snake is controlled by cursor arrows. The objective is to eat as much food as possible and not to collide into the snake's body or the boundaries. Before the game starts, it's possible to set the appropriate size of the console window, the boundaries and the speed of the snake will adjust. After collision, the program will display the total score and ask whether you want to play again.
