Yoshi Topsy-Turvy

Yoshi Topsy-Turvy (released as Yoshi's Universal Gravitation in Europe and Australia) is a title for the Game Boy Advance developed by Artoon and published by Nintendo. It takes place in the present, unlike many other games in the Yoshi series. It was released on 2004 in Japan, and a year later in the United States. This was one of only a few Nintendo games to feature gyroscopic controls built into cartridges, some others being WarioWare: Twisted! and Kirby Tilt 'n' Tumble.

Story
Bowser and his armies were attacking Yoshi Island, causing chaos and disorder to the inhabitants. In response to this, a spirit named Hongo attempts to seal Bowser and his minions in his book named Forbidden Pop-Up Book to stop Bowser's destruction, but Hongo fails and accidentally seals the entire island in the book. Yoshi starts panicking, but a spirit named Spirit Who Loves Surprises explains to Yoshi that he must talk with Hongo and convince him to bring Yoshi Island back to normal, because spirits don't have enough power to defeat Bowser, which was hiding in a cave at the final chapter of the book, The Tale of Bowser's Cave. He also says that he was fired because he didn't know how to keep secrets. Yoshi gets mad, and has a proof of his apology, the Spirit Who Loves Surprises gives to Yoshi the power to tilt the entire world and explains how to use it, but Yoshi accidentally hits the spirit with a boulder. Yoshi manages to convince Hongo to restore Yoshi Island under the conditions that Yoshi must defeat Bowser, because if he restore Yoshi Island with Bowser, he will attack Yoshi Island again. Now Yoshi must satisfy each one of the Yoshi Island Spirits. By doing this, he will receive Happiness Medals and the spirits will allow him to battle with Bowser.

Yoshi finds the Spirit of Cuteness, which explains to Yoshi that Bowser attacked Eggland and transformed every Eggling into apples. When Yoshi swallows an apple, it is revealed that the apple is really a Eggling. After completing four chapters and satisfying some spirits, Yoshi must complete a level where a Fake Bowser tries to attack him; it turns out that the Bowser is actually being controlled by the Spirit Who Loves Surprises. Yoshi gets mad, but the Spirit Who Love Surprises apologizes for frightening him and says that he was just testing him to see if he is ready to battle with the real Bowser. After completing this level, Yoshi must complete two more chapters. When Yoshi has satisfied every spirit of Yoshi Island, he can battle with Bowser.

After completing the spirits' missions, rescuing the Egglings, and defeating Bowser, the spirits celebrate Yoshi's victory, and Hongo gets very grateful for Yoshi's heroism. He makes a meal for Yoshi, but Yoshi still wasn't happy. He then uses his magic to bring Yoshi's Island back to normal and Yoshi back to its original state. Yoshi eats the meal with the Egglings, which will never forgot Yoshi's deeds. At the end, the Spirit Who Loves Surprises returns to work with Hongo.

Gameplay
This is the first Mario and Yoshi game in which gravity plays an important role. By tilting the Game Boy Advance left or right, the game world tilts accordingly. There are only three levels of tilt: normal, left, and right. Fine-tuning of the level of tilt was not present. When the world is tilted, Yoshi can walk on walls, and many items such as Chime Balls and enemies like Spikeballs roll downhill. The player can also make some objects go upside-down by continually changing the tilt direction.

To go to the next area, Yoshi must touch a ring made of stars. If Yoshi touches one, he cannot go back to the previous area because there is no ring to take him there. At the end of the level, Yoshi must touch a large star to win a Happiness Medal and go to the next level. Some areas require Yoshi to transform into a different form to collect items and reach the end of the level.

Depending on what level of the game players are at, the spirit who give the mission and the requirements for finishing the level change. Every level has a task given by one or two spirits, to increase the difficulty.

The game features a Bonus Games mode, in which Shuffle Mode, Shuffle Mode EX, and other minigames can be played, as well as an Eggling Book. At the end of every level, there is a Bonus Chance!, which is a chance to play a Bonus Mission!. If Yoshi completes a Bonus Mission!, he wins 50 Coins.

Throughout the game, Yoshi will find twelve different enemies which drain his health meter if he touches them. Yoshi can swallow hearts to restore one point of his health meter; a larger heart completely restores Yoshi's health meter. These enemies play important roles in the game; missions given by the Spirit of Power involve defeating a certain number of enemies, and missions given by the Spirit of Kindness involve not defeating enemies. Unlike in other Yoshi games, Yoshi farts after eating an enemy instead of making eggs.

If Yoshi completes the task given by the spirit, he wins a Happiness Medal. If Yoshi completes the level with a much better score than that required, he wins a Gold Medal.

Reception
The game received mediocre reviews. As of August 8, 2006, the game’s overall review score was 6.2/10 based on GameRankings collection of reviews.

IGN’s Craig Harris noted that the use of the star rings to travel through areas made the game seem rigid as some areas only lasted for seconds. He said that the characters were irritating, the storyline was stupid and the gameplay barely resembled other Yoshi games. They also caused the reviewer frustration when used in ways that made it seem like the developers were making sure players learned to pay attention. He also said that this game is the worst game that Nintendo published to the Game Boy Advance, the tilting concept makes everything feel forcefully clumsy, and that the level design is "all over the quality spectrum, from somewhat challenging to ridiculously stupid". He gave the game a 5/10, or "Mediocre".

GameSpot’s Justin Calvert stated that the adventure was fun and clever when it began, but after a while, the graphics, sounds and gameplay mechanics became repetitive. He said that the game is very short, and that he had little reason to keep playing after meeting the bare requirements for beating the game. He also commented that the areas which require transformations to complete are the most enjoyable in the game. He gave the game a 6.6/10.

1UP.com’s Jeremy Parish stated that the game felt like it had been designed around the motion sensor, unlike WarioWare: Twisted! where it felt like the sensor was designed to fit the game. He felt that the game was sub-par, with choppy tilt-sensing technology thrown in. He gave the game a 4/10.
