Kaiju is a game engine, primarily focused on 2D game development, built using the Rust programming language. It aims to provide a robust and flexible framework for creating games, emphasizing performance, ease of use, and a modern development experience. The project is actively developed and maintained, with a clear focus on providing a comprehensive set of features and tools for game developers.

The engine's core architecture is built around several key components. These include a rendering system, handling the display of graphics; an input system, managing player interaction; a physics engine, simulating realistic movement and collisions; and a scene graph, organizing game objects and their relationships. Kaiju leverages the power of Rust to achieve high performance, memory safety, and concurrency, making it suitable for a wide range of 2D game genres, from simple arcade games to more complex experiences.

The repository provides a well-structured codebase, with clear separation of concerns and a modular design. This allows developers to easily understand and extend the engine's functionality. The project also includes comprehensive documentation and examples, making it easier for newcomers to get started and learn the engine's features. The documentation covers various aspects of game development with Kaiju, including setting up the development environment, creating game objects, handling input, implementing physics, and managing game states.

Key features of Kaiju include support for 2D rendering with a focus on efficiency, utilizing techniques like batching and optimized texture management. It offers a flexible input system that supports various input devices, including keyboard, mouse, and gamepads. The physics engine provides collision detection and response, enabling realistic interactions between game objects. The scene graph allows for hierarchical organization of game elements, simplifying scene management and object transformations. Furthermore, the engine provides tools for asset management, including loading and managing textures, sounds, and other game resources.

The project's development philosophy emphasizes community involvement and open-source principles. The repository encourages contributions from the community, fostering collaboration and continuous improvement. The project's roadmap outlines future development plans, including enhancements to existing features and the addition of new functionalities, such as support for more advanced rendering techniques and improved editor tools.
