So I picked up this game 5 or 6 weeks ago, played it for about 10 minutes, and then forgot completely about it. It wasn't particularly bad for a 99 cent game, just uninteresting. Anyway, I heard somewhere that the game is a lot more fun when playing with your music, so I ipodded up some Blink (hah!) and began playing again. Holy crap, Vektrax is so much more fun with your tunes playing. The game itself doesn't change like I had hoped/heard (I thought the paths or colors would somehow correspond to the music), but it's still a much more fun experience and I'll be definitely playing this game casually. But ONLY with the ipod blaring alongside. I'll give it 4/5 stars, up from 2.5.
