PipEngine 2D is a small 2D engine / framework. It based on allegro but I will change soft to openGL
It's simple demo of pipEngine 2D with TRON like gfx. I'm programming it for only 1 week and it's veery simple (I don't have a lot of experience so, I can't do it quickly :D). I'm build it only for windows but on wine it's running well (tested on ubuntu (pl) 11.10) So, if You want to test it, download and write comment! Sorry fot probably crash on startup... As reward I give you an updated version with sound! (and some "hidden" WiP feature :D)
