I played the older version 5 years ago. I've Played it again. And the deluxe. I am ADDICTED to both. The newer version has better sound and more challenges. I think they bothe need a 5. Few games are this much fun after so many years.
shift d = double track
shift s = single track (convert from Double)
hold shift to lay track or release Num Lock = build track
