Like most other games in the Zelda series, Spirit Tracks is great, but it still has its flaws.
The games backstory is like this: Many years ago, the evil Demon King appeared and caused chaos. The spirits tried for many years to stop him, until eventually they subdued the Demon King and sealed him, then locked him with the Spirit Tracks as shackles and the Tower of Spirits being a lock.
Spirit Tracks starts you out as an apprentice engineer (Hint: Its Link) who will soon be leaving to the Castle to graduate and become an engineer. Your trip to the castle is the first time you get to use the train. Later on in the game, you get a cannon, and eventually a freight train, but currently you only have a passenger train and the main car. There are four car options- Stop, Reverse (Also works as an emergency brake) Forward, and Fast Forward. You also have a whistle, which has multiple purposes, from calling Beedle over to making portals through the time-space continuum. Anyway, as you finally reach the Castle, a series of events leads you to meeting Zelda in her room and helping her escape. This marks the first time Zelda has ever been playable (excluding the CD-i game) To control her, you draw a line to where you want her to go. After you get her past the guards and into your train, she'll ask to go to the Tower of Spirits. Sounds easy, right? Things go downhill quickly.
You, Zelda, and Alfonso (Your engineer teacher who bears a resemblance to one of Tetra's pirates) are riding to the tower, but the tracks suddenly disappear under you. The train crashes, and a short fellow with two hats named Chancellor Cole appears, with a man who has a metal fist. Cole is actually a demon, and needs the body of one of Hyrule's royals to house the Demon King's revival. And who do we have with us? Princess Zelda. Link and Alfonso are knocked out, and Zelda actually gets her spirit kicked out of her body. Link wakes up in the Castle, finds Spirit Zelda, and the adventure begins.
Now, you go through the Tower of Spirits to unlock new tracks and areas. Here, you collect Tears of Light, so you can hit Phantoms and then have Zelda control them. Phantoms are big suits of armor that are incredibly strong and nearly invincible. The Tower of Spirits is like the Temple of the Ocean King from Phantom Hourglass, but you no longer have to repeat levels every time you go through. That is a plus. There are a few new items, like the Whirlwind, a fan you blow into the mic to use, or the Spirit Flute, which you can play like a real pan flute. There are also old items, like the bombs or the boomerang.
This game does have flaws, though. Zelda, when not in a Phantom, is usually annoying. The train levels have much less exploration, because you have to go on the rails. From time to time, you will unlock new rails, but there is still not the same exciting discovery from Phantom Hourglass. There are fewer dungeons, and there is no Wi-Fi for battles.
Despite these flaws, I like Spirit Tracks, and it is a good game. I highly hope you buy it and enjoy it. Thank you, and that was my review.
