This is a game where you drive a train through the a musical
version of the Tokyo Subway. If you stay on the track the
music plays, make a mistake and you'll mess up the music.
The goal of the game is to drive a Tokyo Subway car through the maze of routes and make it to the final
stop with the fewest deviations from the track (in my world, the trains don't stay on the tracks unless
you steer them). It's a bit like Centipede or Snake, but with a train track and music integrated into
the game play.
The movement of the train is synchronized to a song - with every beat of the song, the train advances a
hundred feet down the track. As long as you stay on the track, the song will play perfectly, but if you
miss a turn, not only will you veer off the tracks you will also veer into a completely different part
of the song. If you stop the train, the song will stop and continually play that one beat until you
start again. If you go backwards the song will play backwards. You can speed the train up and slow it
down (which, of course, also speeds up or slows down the song). A faster train is harder to drive but
gets you to the destination quicker.
You get points for good driving and getting to the destination in
the quickest time. There's an adjustable headlight on the train - the brighter the headlight, the
further ahead you can see, making the drive easier, but the headlight uses lots of energy, so a brighter
headlight will cost you a number of points. You can also drive during the day letting you see the whole
line stretched out in front of you. It's much easier to navigate, but driving during the day costs more
points than (access to the tracks during the day is very expensive in my train system). There's even an
autopilot that will take over and drive the train perfectly for you, but it chews through points very
rapidly, so use it sparingly.
