Audiosurf

Audiosurf 1.0.0 is a game where you´ll need to match same colored blocks.
You´ll need to have Steam Installer from Valve installed to be able to install Audiosurf.

So, if you don´t, you will be directed to Valve´s Site to download it. After that, you must create an account. Then, you´ll be able to install the demo version.

The first screen that will be shown displays some music news.

The object of the game is to make matches of three or more blocks of the same color. You pick blocks touching them with your vehicle, that you control with the cursor movement keys. That vehicle runs a highway that is made according to the music (CD or MP3) that you have chosen, so there is an infinite amount of possibilities.

There are some power-ups along the road, that you can pick, like black stones or energizers.

Once the song finishes, so does the game. Steam looks for another player that have played with the same song than you, and compares scores. You can enter your name in the high scores list if you want.
