This review is from: Phineas and Ferb - Nintendo DS (Video Game)
My 9 year old son who is brand new to handheld video games says "It's about building a huge roller coaster. It's pretty fun but in some places it's kind of hard to use the controls. The building parts are really fun." My 6 year old says "It's a little hard for me to play because of finding the stuff in the boxes."
