raylib

raylib is a simple and easy-to-use library to enjoy video game programming. It is a programming library to enjoy video game programming; no fancy interface, no visual helpers, no GUI tools or editors, just coding in a pure spartan-programmers way. raylib does not provide the typical API documentation or a big set of tutorials. The library is designed to be minimalistic and be learned just from a cheat sheet with all required functionality and a big collection of examples to see how to use that functionality. The best way to learn to code is by reading code. raylib supports multiple target platforms, it has been tested in the following ones but, technically, any platform that supports C language and OpenGL graphics (or similar) can run raylib or it can be very easily ported to. You can use raylib with multiple programming languages, there are over 60 bindings. raylib can be combined with several extra libraries for additional functionality.
