🐍 Snake Game (C++ / Raylib)

A modern take on the classic Snake game, built in C++ with Raylib for rendering and CMake for build automation.
The project features clean architecture, interactive UI, multiple levels, and robust unit tests powered by Catch2.

✨ Features

• 🎮 Controls: W, A, S, D
• 🍎 Moving food — makes gameplay more challenging
• 🔰 3 levels with unique layouts
• 🟢 Rendering & UI with Raylib
• 🧪 Unit testing with Catch2
• 🧱 OOP Game Patterns: Command, Game Loop
• 🧩 Layered design → {core logic} + {render} → {game logic} → game loop
• 📁 Clean folder structure with CMake build system
• 📄 Doxygen documentation
• 📑 Clang formatting for consistent code style
