So it sounds like the source code for game is written in pure javascript (utilizing any special APIs calls provided by Impact). This javascript src is packaged using the Impact Game Engine which creates a Obj-C wrapper around the javascript. When the Game is loaded on an iOS device and run, the Obj-C wrapper (implemented by Impact) executes the javascript src via JavascriptCore. It sounds like this is basically a Canvas to OpenGL translation layer. Can only the Canvas object be leveraged when creating games/apps with this? Or could a "account creation" screen be created leveraging HTML elements like forms (I would assume not since its sounds like its executed outside of Safari, and the translation provided is from Canvas > OpenGL)
