Sonic the Hedgehog 2 is now available for Android and iOS devices, featuring a host of improvements and additions including graphical enhacements. I cannot see a noticeable difference in graphics; the more interesting features include the ability to play as Tails or Knuckles and the addition of the long-lost Hidden Palace Zone.

You can check out the trailer for Sonic the Hedgehog 2's re-release below.
