YMMV / Yoshi's Universal Gravitation

• Funny Moments: The intro, when The Spirit Who Loves Surprises gives you the power to alter gravity. He asks you to test it out on a boulder a short distance away from him, and most likely, you will immediately send the boulder crashing into him, sending the Spirit blasting off like Team Rocket, A Twinkle in the Sky and all! Unlike Team Rocket though, he praises you for figuring out the power while flying off because of it!
• Germans Love David Hasselhoff: The game seems to be better regarded, or at least better known in Europe, if only because out of the four portable Nintendo games to use a tilt sensor (the other three being Kirby Tilt 'n' Tumble, WarioWare: Twisted!, and the obscure 2002 offering Koro Koro Puzzle Happy Panechu!, which never left Japan in the first place), it was the only one to actually reach European shores. As a result, this was the only time that Europeans got to experiment with such a control scheme, instead of simply being one in a line of similar games. It is unknown if Kirby Tilt 'n' Tumble was ever considered for an European release, and the last word we got of a possible EU release for WarioWare: Twisted! is that it was still undergoing safety testing at LGA. A criticism of Universal Gravitation is that Twisted! supposedly implemented the tilt sensor better, but of course Europeans never got to experience that.
• Memetic Mutation: "But Yoshi was not amused." ^explanation A frame from the ending cutscene that became popular as a reaction image.
• Nightmare Fuel: If a Piranha Plant gets Yoshi on his last hit point, you hear the poor dinosaur's death yell while the plant chews him up. Just as the death jingle ends and a split second after Yoshi's green flower drains all color and turns blank-faced with eyes closed, the plant starts chomping air again, meaning it either swallowed the dead dino or is chomping him up harder!
• So Okay, It's Average: This is what professional critical reviews of the game mostly boiled down to. The majority seemed to agree that it was a decent platformer with nothing offensively bad about it, but the level design was somewhat uninspired and the tilt controls proved polarizing. The fact that it came out at the end of the GBA's lifespan, when the Nintendo DS had already released, hurt its sales.
