Great news! With some help of Brainzyy of the Porting Kit forums, we managed to add Audiosurf for Mac to Porting Kit and Crossover (was already added in there). This very popular game works great! Happy gaming!
Ride your music. Audiosurf is a music-adapting puzzle racer where you use your own music to create your own experience. The shape, the speed, and the mood of each ride is determined by the song you choose. You earn points for clustering together blocks of the same color on the highway, and compete with others on the internet for the high score on your favorite songs.
