The PacMan GUI Game is built with a Java logic backend and involves using a Java Swing/AWT. It allows users' keyboard inputs convert into real-time character movements that can functional properly and play Pac-Man logically. Interface UI is made under nostalgic arcade theme, allows user input, direction choices convert into active maze navigation and score progression while being able to safely store data.

• Smooth Visual Rendering: Game frames are updated instantly according to keyboard inputs, providing a smooth experience without lagging the grid canvas interface.

• Data Saved in State: All high scores and current session configurations are stored in an active runtime engine which ensures that records survive under game loop cycles and remain accessible to all. Results are also shown and updated accordingly to users.

• Easy to use: The interface is direct, user-friendly, and utilizes a retro, high-contrast palette.

• Dynamic Ghost Tracking: Navigate any path you wish to take and the application's backend will generate real-time tracking movements and map it to your target destination. While ghost is moving through a random movement generator.

• Interactive Maze Grid: The structural map outputs to users as a result which is a fully functional layout grid that safely processes asset consumption like pellets and fruits.

• Instant Replay Engine: A built-in collision/reset feature instantly clears the previous board data and toggles the UI back to its default start state, allowing for rapid, back-to-back game sessions.

Creating the interface involved making a container that stores the maze layout, character sprites, and status displays through utilizing a classic retro color palette. Drawing dimensions and custom graphics contexts (Graphics2D) were heavily utilized to manage the aesthetic arcade theme.

The frontend relies on using the KeyListener undergoing The Tick/Game Cycle to communicate coordinate variations to the movement thread synchronously. This means taking the user's keystrokes, encoding it and sending it to a direction assessment handler in Java.

Game development project had to consider ensuring data survival while variables update. Initially I relied on using standard 2D arrays in the backend architecture to store static wall maps through structural matrix indices and later was upgraded to use custom game objects. By creating custom coordinate records, entity classes which store positional states and created through using OOP framework. Boundary analysis logic manages map collision conditions behind the scenes. This allows the internal tracking array to persistently manage every generated coordinate point on the memory stack.

Finally, for the user interaction, I use game state switches to create toggle operations to pause active play screens after 'game over' statuses using conditional painting techniques and instantly show the final scoreboard output.

• Game Engine Integration: I've learned how to build a bridge between a real-time drawing panel and an operational thread framework using frame rendering patterns.

• Object-Oriented Game Architecture: Moving beyond static arrays, I learned how to use independent model entities to automatically create and manage characters, maintaining spatial coordinates across movement states.

Built with standard Java Swing and Graphics framework components.
