fans of the original Yoshi's Island may be a bit dissapointed, but there's no denying this is a polished game.
Yes, the game is easy. Too easy. but it isn't the individual levels that make it so easy. In fact, some of them can be challenging. But it is more or less the fact that the game only makes you play though 6 of the games 24 levels to beat the game! Those who beat a game once and then put it away, do not even THINK of buying this game unless you either suck at 2-d platformers (be honest) or take levels very slow. Had the programmers bothered to link all the levels together, the game would probably of lasted about 30 hours to beat the first time. As it stands, you will most likely beat the game in a determined afternoon.
But that's not to say there's no replay value. The game has four levels at each world, of increasing difficulty from 1 to 4. That means you can beat the game four times and not get bored because each time you have a different level to look forward to! this alone should take the amount of time you spend on the game to 30 hours at least. There. Enough blathering over time consumption. On to the other things.
Playing the game is quite simply a joy, and moving yoshi with the control stick allows a you to move with ease. You can also turn yourself into an egg, turn enemies into eggs and throw them, pound the ground, and sniff any area of the level to find secrets! While some courses can be unoriginal (the standard snow level comes to mind), all of them have at least a spark of enginuity, and the best ones seem to be all in their own. Another thing is collecting hearts so that you can play all the levels in all the worlds. Another thin is the two mini games that it has in store. I won't give them away, but they are a hilight of the game.
Finally, we come to graphics and sound. Sound, while nothing to write home about, is quite pleasant with a good assortment of enemies noises, good sound effects and toe tapping (but occasionally annoying) music with a wide range of stiles. Graphics are where the real show is, with levels that seem to be made out of cardboard (complete with perforated edges, rips that have been taped together, and many other details) levels made of throw pillows and jeans (complete with seams and pockets), and the list goes on and on. Also, almost every charactor is nicely animated and pre-rendered in 3d, giving the game a very nice look and feel.
All in all, yoshi's story is a game with a LOT of replay value, and while easy, at least it's not ridiculously so (like kirby 64, but that's not to say it's not fun). At the end of the day, this game is good, simple fun that can be enjoyed by all.
