Frustration grabs you every level but Yoshi's Island DS will suck you in with it's great gameplay and graphics.
My only problem was that I had to pull my hair out and get the buttons to leave imprints on my thumb on how frustrating the levels were.I just found them so infuriating because I had to do the same part over and over because the makers didn't place the save points very brightly. Another thing was the way you got extra lives. I mean spin a wheel to see if you get one. I think they should have just made us collect them but place them in hard spots.
To conclude, Yoshi's Island Ds is very frustrating but it never leaves you too frustrated to make you give up on it.
