The Sound Walk Fun fun fun... then a bit of a downer.
The idea was awesome, and the music was great. The problem I had with lag was brought into line (though not fixed). The real problem I had was that there was such an interesting story to be told here... and it wasn't told. I'm not sure if I simply don't deserve a story, since I didn't buy the game, but it was still a bit of a letdown to work so hard to beat the game, so that I could see the conclusion, only to be shot down. Still, I had some fun playing once the lag was held down, so it wasn't a complete sad time.
