The iPhone's design hasn't changed a great deal from the 6S, with
the only significant alterations other than the loss of the headphone socket being the larger and more protruding camera lens, and the two speaker grilles at the bottom of the phone.
In fact, this is probably the
only major change to the basic fabric of Super Mario Galaxy 2 from its predecessor; new power - ups and
alterations to the world map are notable, but Yoshi is by far the most
significant new feature.
