A classic PacMan arcade game built from scratch in Java using Swing.

Watch the ghosts coordinate using Agentic AI (LangGraph & Ollama). They communicate, debate, and coordinate their hunting strategies in real-time. No gimmicks, just pure LLM-driven multi-agent pathfinding.

Watch the Demo: https://res.cloudinary.com/eiss6qy0/video/upload/v1783707203/Setting_up_hhkijr.mp4

• Navigate PacMan through the maze eating all the dots
• Avoid the 4 ghosts — Blue, Red, Pink, and Orange
• Eat all pellets to advance to the next level
• You start with 3 lives — lose them all and it's game over
• Press any arrow key after Game Over to restart
