The game uses side-scrolling platform action focused on speed, jumping, rolling, and momentum control. Compared with the original release, it introduces altered physics, distinct playable characters, and more exploration-heavy stage routes. Levels combine enemy avoidance, item collection, branching paths, and hidden areas. Progress is typically linear through stages, but route choice and character selection can change how each area is approached.
Sonic
The speed-focused lead character, best for fast route execution and momentum-based play.
Tails
Aerial mobility lets him reach alternate routes and hidden areas more easily.
Knuckles
Strength and climbing abilities make him useful for exploration and shortcut discovery.
Learn each character's strengths before pushing for speed. Sonic is best for memorizing stages and carrying momentum, Tails for safer route checks and hidden-item hunting, and Knuckles for vertical exploration. Don't overcommit to full speed on unfamiliar terrain; many hazards appear after slopes or springs. Rings are valuable insurance, so keep a comfortable buffer whenever possible.
