Audiosurf is probably one of the best music based game (aside from Beat Hazard Ultra) on the PC right now, and while the team had some difficulties porting the game over to the Iphone/Ipod touch, it doesn’t mean that they’re not working on the next step.
A website has appeared for something called Audiosurf Air, which we can only assume that it is a sequel to the use-your-own-music-racing-puzzle game. The site includes some screenshots that look exactly what you’d expect from Audiosurf, and the option to sign up for the beta, you can click here to see the site for yourself.
