I have to build a 2D game with tons of animated objects inside it and a continuous background music. The problem is that I will need to use it inside a mobile application (I will use CrossWalk Project) so the performance are reaaaally important for me!
My first choice was the famous.org project, but it seems they shut down the development. I already built a prototype in svg using snapsvg, but It's a bit laggy. I've seen that pixi.js claims itself as the fastest game engine, but I'm not so sure about that.
