Changes from this game to Super Mario World 2: Yoshi's Island
The game added the voice of Kazumi Totaka as Yoshi's voice, whereas in the original the dinosaur just made simple grunts. The voice samples were taken from the Nintendo 64 game Yoshi's Story.
Six new levels titled "secret levels" that were increasingly harder than the standard levels.
The stage More Monkey Madness no longer has twenty-one Red Coins, but just twenty.
Reviews of the game were generally favorable. GameRankings.com has collected various game reviews and have decided that the average rating is 89.49%. IGN rewarded the game with an impressive 9.4/10, stating that it has "some of the most clever, brilliant, and versatile level designs...it is one of, if not the best 2D platformer ever designed." Unfortunately, of the four games released in the Super Mario Advance series, Yoshi's Island fared the worst, selling 2.91 million. While impressive, the other games have sold nearly twice that amount. Super Mario Land and New Super Mario Bros., two other 2D Mario platformers for a Nintendo handheld (Game Boy and Nintendo DS, respectively), both sold over 18 million copies.
