🐍 Hand-Tracked Snake Game

A modern twist on the classic Snake game — play using just your index finger, tracked in real-time via your webcam! Built using Python, OpenCV, pygame, and cvzone.

🎮 Features

• 🖐️ Hand Gesture Control: Move the snake using your index finger — no keyboard needed.
• 🍎 Multiple Food Types: Randomly spawning banana, apple, and donut images.
• 🐍 Snake Growth Mechanism: Each food increases your snake’s length.
• 💥 Game Over Logic: Collision with the snake’s own body ends the game.
• 🔊 Sound Effects: Fun sounds play when you eat or collide.
• 🧠 High Score Memory: Highest score persists across sessions (stored in score.txt).
• 📸 Live Webcam Feed: Integrated directly into gameplay using OpenCV.
