About Sonic Mania
Sonic Mania is a side-scrolling platformer that pays homage to the original Sega Genesis Sonic the Hedgehog games. Players choose from Sonic, Tails, or Knuckles, each with unique abilities, and speed through 13 zones that include redesigned stages from past games alongside original levels. The game features special stages for collecting Chaos Emeralds, time attack with online leaderboards, and split-screen competitive multiplayer.
