yup a fun as hell game that pwns the very fabric of time audio surf is a unique game that uses the music of your choosing to your advantage as the game suggests ''ride your music'' you really can absorb that very feeling of epicness. as long as you have somthing to run you music on ''i suggest limewire the free version not pro'' the more fast paced and urgent the song is the faster the track is and harder its going to be. however if your in the mood for calming and relaxing music the more easy and slower the track is. although there is a task rather that just riding through a track.in the track there are lanes with blocks in them the harder the track the more lanes. there are technicly 2 game modes one is mono all there are is grey and clolerd blocks avoid the greys get the cloerd simple the other one is a bit more complex. there areno greys and instead of colered blocks the blocks are a unique colour representing how much there worth. dont let the troll face trick you its a must buy.
