Orx is a lightweight, open-source 2D game engine written in C, designed for data-driven development. Its configuration-based system uses INI-like files for game logic, minimizing code for rapid prototyping. Orx supports sprites, animations, and physics, ideal for platformers or arcade games. It targets Windows, macOS, Linux, Android, and iOS, with a plugin system for extensibility. Without a visual editor, it suits C/C++ programmers, though its API is beginner-friendly. The community provides tutorials and forums, though smaller than Godot’s. Orx’s performance and portability make it perfect for indie developers creating retro 2D titles. Its BSD license ensures no restrictions, but 3D support is absent. Actively maintained, Orx balances simplicity and power.
