UntitledEngine is a small 2D game engine that uses SDL and openGL. its right now in pre-alpha stage.All it can do now is render some images and animation,manage states and handle keyboard input. but as time passes I hope it will grow bigger .right now only two programmers are working on it.
So if you want to contribute to the project please contact me
