This is pretty great! The feeling of speed is excellent and it's very dynamic with the camera changes. Could work great like some 2D wipeout thing, with a more limited track which you can fall off of, etc.
How is it done? Is there a predefined track with certain points that trigger a "camera" change or is it random as of now? Either way, quite cool, would be interested in seeing a .capx.
I was thinking of something similar recently, with a "lane switching" sort of feel to it, but not with such a dynamic camera. That really adds to it.
