A good sequel to the original. It has all the good things the old game had, but at times it can be extremely difficult.
Bad:The only thing that I didn't like (and this is a major thing) is that it gets extremely difficult very quickly. The first 3 worlds are fairly simple. Then when you get to the 4th and the 5th world it gets very frustrating. There were times when I felt like either throwing my DS out the window or punching a baby in the face. There are some levels where you have to stay on a small platform made of slippery ice while there are ghosts flying at you and you have to try to save your baby that is floating away all at the same time.
Overall, I would say this is a really good game. Maybe its just me, but this game was fairly hard to beat in the end. Its a lot harder than the original. (I beat the original in about a week and it took me about a month to beat this game.) But if you are at all a fan of the original Yoshi's Island or platforming in general, then get this game. But be warned, it may be very frustrating...
