3/5 ★ – gocki's review of Audiosurf.

It is nice that you can use your own music files to generate levels. However the visuals are quite dull and due to the concentration I needed for the puzzle mechanics I was not able to get into some kind of flow like in classical puzzle games. When looking for a rhythm game where you can use your own music, I would rather recommend Beat Hazard, although it has arcade gameplay instead of puzzle mechanics.
