# About Classic Snake Game

Classic Snake Game is a modern rendition of the beloved arcade game, built using HTML5 and JavaScript. The objective is simple yet captivating: guide an ever-growing snake to consume food pellets, increasing your score and the snake's length. As the snake grows, navigating the game area becomes more challenging, testing your reflexes and strategic thinking. The game ends if the snake collides with the boundaries of the play area or its own body. This version features a clean, minimalist design, responsive layout for various screen sizes, and intuitive controls for both desktop and mobile play.

The game board is a grid, and the snake moves one grid unit at a time. Food appears randomly on the grid, and your goal is to direct the snake to eat it. Each piece of food consumed not only adds to your score but also makes the snake longer, increasing the difficulty. The game begins with the snake having an initial length of three segments.

## How to Play

The game starts with a short snake on the screen.
-   **Objective:** Control the snake to eat the red food items that appear on the screen.
-   **Growth:** Each time the snake eats food, it grows longer by one segment, and your score increases by one point.
-   **Movement:** The snake moves continuously in its current direction. You can change its direction up, down, left, or right. The snake cannot immediately reverse its direction (e.g., if moving right, you cannot immediately go left).
-   **Game Over:** The game ends if the snake's head collides with the walls of the game area or any part of its own body.
-   **Starting/Restarting:** To start a new game or restart after a game over, press the 'Enter' key or tap the screen when prompted by the on-screen message.

## Features

-   **Timeless Gameplay:** Enjoy the addictive and straightforward mechanics of the original Snake game.
-   **Responsive Design:** The game automatically adjusts its play area (grid size) to fit your screen, providing an optimal experience on desktops, tablets, and mobile phones.
-   **Dual Control Scheme:** Play using arrow keys on a desktop computer or intuitive swipe gestures on touch-screen devices.
-   **Dynamic Score Tracking:** Your current score is displayed in real-time at the top-left of the screen.
-   **Clear Visuals:** Simple and clean graphics ensure focus on the gameplay, featuring a lime green snake and red food on a dark background.
-   **Randomized Food Placement:** Food appears in unpredictable locations on the grid, ensuring it doesn't spawn on the snake's body, keeping each game session fresh and challenging.
-   **Adaptive Game Board:** The number of tiles on the game board (tileCountX, tileCountY) is calculated based on screen size, ensuring playability.

## Controls

-   **Desktop:**
    -   **Arrow Up:** Change snake's direction to Up.
    -   **Arrow Down:** Change snake's direction to Down.
    -   **Arrow Left:** Change snake's direction to Left.
    -   **Arrow Right:** Change snake's direction to Right.

    -   **Swipe Down:** Change snake's direction to Down.
    -   **Swipe Left:** Change snake's direction to Left.
    -   **Swipe Right:** Change snake's direction to Right.
    -   **Tap Screen (on message overlay):** Start a new game or restart after game over.

## Tips & Strategies

-   **Plan Your Route:** Especially as the snake gets longer, think a few moves ahead to avoid getting trapped by its own tail or the walls.
-   **Use the Edges Wisely:** The walls are game-ending obstacles, but sometimes moving along an edge can help you manage your snake's length temporarily. Be cautious not to corner yourself.
-   **Controlled Turns:** Avoid making rapid, unnecessary turns. Smooth, deliberate movements are key to survival as the snake grows.
-   **Don't Rush for Food:** Sometimes, it's better to make a safe turn or maneuver into a better position before going for the food, especially if it's in a tight spot or near your tail.
-   **Perimeter Strategy:** Some players find it easier to circle the outer edges of the board and spiral inwards as the snake grows, but this requires careful planning.
