# About HTML5 Snake Adventure

This game is a modern take on the universally loved classic, Snake. Built with HTML5 and JavaScript, "HTML5 Snake Adventure" offers the nostalgic gameplay you remember, enhanced for today's browsers and devices. The core objective remains simple yet addictive: control a continuously moving snake, guide it towards food to grow longer, and skillfully avoid colliding with the game borders or the snake's own ever-extending body. As your snake grows, so does the challenge, testing your reflexes and strategic thinking.

The game features a clean, retro-inspired visual style with a distinctively colored snake head, a vibrant green body, and bright red food items, all set against a dark, immersive background. It's designed to be intuitive and engaging for both seasoned Snake players and newcomers.

## How to Play

You start as a small snake on a grid-based play area. Your primary goal is to navigate the snake to consume food items that appear randomly on the screen. Each piece of food eaten makes the snake grow longer and increases your score.

The game ends if the snake's head collides with the edges of the play area or any part of its own body. As your score increases, the snake's movement speed will also gradually increase, adding to the difficulty.

To begin a new game or restart after a game over, simply press the 'Enter' key, 'Space' bar on your keyboard, or tap the screen if you're on a touch-enabled device.

## Features

- **Classic Core Gameplay:** Experience the timeless fun of Snake with its simple controls and engaging, addictive mechanics.
- **Responsive Design:** The game automatically adjusts its canvas size to best fit your screen, whether you're on a desktop, tablet, or smartphone. (Note: resizing during gameplay will reset the current game).
- **Dual Control Scheme:** Play comfortably using Arrow Keys (or W/A/S/D) on a keyboard, or intuitive swipe gestures on touch-enabled devices.
- **Dynamic Difficulty Curve:** The game speed subtly increases as you consume more food, keeping the challenge fresh and rewarding for players of all skill levels.
- **Clear UI Elements:** Enjoy instant score updates, a prominent message display for game status (start, game over), and a helpful controls hint.
- **Retro Aesthetics:** Immerse yourself in a clean, retro-inspired visual style with a distinctively darker green snake head, a bright green snake body, vibrant red food, and a classic black game background.

    -   **Arrow Down / S:** Move snake Down
    -   **Arrow Left / A:** Move snake Left
    -   **Arrow Right / D:** Move snake Right
    -   **Enter / Space:** Start or Restart the game

    -   **Tap Screen:** Start or Restart the game (when on the welcome or game over screen)

## Tips & Strategies

- **Plan Ahead:** Don't just chase the food. Think a few moves ahead, especially as your snake gets longer and maneuvering space becomes limited. Anticipate where the food might appear next.
- **Use the Edges Wisely:** While walls are deadly, you can use them to guide long segments of your snake. However, be extremely cautious not to trap yourself.
- **Master Quick Turns:** Practice changing direction efficiently. Avoid making immediate 180-degree turns, as this will cause you to collide with your snake's body. The game prevents direct reversal, but quick successive turns need care.
- **Controlled Coiling:** As your snake becomes very long, try to create large, open loops or S-patterns rather than tight, tangled knots. This maximizes your available space and options for movement.
