🦖 Dino Runner Game (LibGDX)

A 2D infinite runner game inspired by the classic Chrome Dino game. Built using LibGDX, this version includes enhancements like dynamic background (moon, stars), road marks, moving clouds, score tracking, and multiple obstacles.

🚀 Features

• 🕹️ Player jump logic
• 🌵 Obstacle spawning (multiple cacti types)
• 🌙 Dynamic moon & stars animation
• 🛣️ Moving road marks and scrolling background
• ☁️ Randomly spawning clouds
• 🎮 Game restart with score and high score
• 📈 Scoring and persistent high score tracking
• 🎨 Optimized for smooth performance and modular design

🎮 How to Play

• Press SPACE or tap to make the Dino jump.
• Avoid hitting obstacles like cacti and birds.
• Survive as long as possible to increase your score.
• After game over, press R to restart.
