Its a indie game released over steam. Its a one man team that made the game.
Its kinda guitar hero meets 80's arcade racer where you have do avoid the other cars

i played the demo and really liked it . the best thing about it that you can use ANY kind of music of your mp3 folder, or cd or itunes.
it analyses the track and makes a imo really good race/play track out of it.
and the cooles thing is that you can keep your track record online and compete with other people i played with beat it from michael and i had about 40.000 points and i thought yeah im cool! and then the points were uploaded and i saw people with 100.000 and up

and so many people played the track.
the full game just costs 9.95 $ its even peanuts for me
give it a try im sure you gonna like it. The demo is for free of course
