Mega Snake : Turbo C++

   Mega Snake is a game in which the player controls a snake, which roams around on a bordered plane. The goal is to score points by helping the snake eat its food, while preventing a collision with the walls or its own tail.

Each time the snake eats a piece of food, its tail grows longer, making the game increasingly difficult. The user controls the direction of the snake's head (up, down, left, or right), and the snake's body follows. The longer you play and the more food the snake eats, the more points you gain. It has been developed using the Turbo C++ 3.0 IDE. It uses BGI Graphics to render all the graphics.
