• 🎯 Score tracking system
• ⚡ Progressive difficulty (speed increases)
• ⏸️ Pause functionality
• 🎨 Clean ASCII art interface
• 📊 Real-time stats display

🛠️ Technologies

• Language: C# 10.0
• Framework: .NET 10.0
• Platform: Cross-platform (Windows, macOS, Linux)

🚀 Getting Started

Prerequisites

• .NET 10.0 SDK or later

Installation & Running

# Clone the repository
git clone https://github.com/ky-cx/snake-game-csharp.git

# Navigate to project directory
cd snake-game-csharp

# Run the game
dotnet run

🎮 How to Play

Controls

• W / ↑ - Move Up
• S / ↓ - Move Down
• A / ← - Move Left
• D / → - Move Right
• P - Pause/Resume
• Q - Quit
