I made a Flappy Bird clone in OpenGL & Raylib. I wanted to make a starting point project with the Raylib and the most basic game came to mind. Flappy Bird. Its one of the most simple games ever created so it will be a good starting point. I first started with the games art, code, then some final touches. It also uses my NetworkML library for file management.
