I'm looking for a library like "cocos2d-x" that abstracts the OpenGL library for 2D games. I don't need to make 3D games, I'm just need all power of OpenGL for a 2D game. The problem with "cocos2d-x" is have a poor support for Linux (not stable only "usable") and requires a relative high version of OpenGL, that means a lot of "middle age" computers will not run the game. Don't matter if such library don't manages sound or events, I can complement this with SDL. Thanks in advance!
