Yoshi's Universal Gravitation (known as Yoshi Topsy-Turvy in Japan and the United States) is a game for the Game Boy Advance developed by Artoon and published by Nintendo. The game is a spin-off of the series of platform games starring Yoshi. It is one of the few games in the Yoshi franchise to take place in the present relative to the Mario franchise, as Bowser appears instead of Baby Bowser. It was released on December 9th, 2004 in Japan, and localized for other markets four to six months later. This was one of the only few Nintendo games released for Game Boy systems to feature gyroscopic controls built into cartridges.
When Bowser starts wreaking havoc on Yoshi's Island, a book spirit named Hongo traps the entire island within the pages of a storybook. Only by locking Bowser away, Yoshi can convince Hongo to release the rest of the island, so he sets out to progress through the chapters of the book.
- THe biggest problem that this game has that Tilt mechanics are very clumsy , and frustrating to use, not to mention that they are very difficult to use. As every single puzzle and platforming challenge in this game is based solely on the new tilt mechanic, Yoshi's iconic ability to throw eggs also takes a back seat.
- The level objectives (eating a certain number of apples, collecting a certain number of coins, killing (or not killing) a certain number of enemies, and completing levels before time runs out) can add to the frustration.
- The graphics are ugly and very choppy even during the 2000s.
- The game is way to short as you can beat the game in 4 hours.
- The transformation levels are brief and manage to become repetitive.
- The bonus games can be completed successfully in as little as three seconds.
- Little to no replay value.
- The artwork retains the crayon aesthetic of Yoshi's Island.
