It's an interesting library, but it's just a wrapper around WebSockets. It also requires setting up a Node.js server to talk to, so is not entirely straightforward to get working.
It might be useful when we come to add multiplayer, but I prefer not to use third party libraries where possible and write our own. This offers the maximum performance and flexibility. If we used a third party game engine library, for example, it's unlikely Construct 2 would be anywhere near as fast as it is with it's WebGL renderer.
