You might know [Audiosurf], and already purchased it long time ago. Visit that link, check official homepage, and you could find 'Web Surf' is available.
[Audiosurf] was great game, but we can't see the playlist / scores / ... etc. from the Web. We could see some chart in-game, but information was very limited. But from now on, we could see them from Web. (And even in Game, which browse that homepage.)
This is good news for every Audiosurfer, but not sure why it's done at now, around 1.5 year has passed after release. However seems to be fun. :)
P.S. : 4.99$ for weekly sale. If you've not got it yet, run to grab.
