Starling JS
The Open-Source Game Engine For JavaScript
... that wasn't meant to be.
Starling JS is now in the hands of the Away3D Foundation

Due to reasons described in this blog post, we had to cancel the Starling JS project. We decided that Gamua should keep its focus fully on the AS3 version of Starling. We're not planning any further ports at the moment. (However, we encourage any community efforts in this respect!)

All the code we had already written for Starling JS has been donated to The Away Foundation instead, who plan to integrate it into their JavaScript library in the future.
