Players control Sonic through side-scrolling stages focused on speed, jumps, spin attacks, and momentum-based movement. Each zone has multiple acts and a time-travel feature that changes layouts, hazards, and enemy placement across Past, Present, and Future versions. By interacting with time posts and collecting Time Stones, players can alter the future and affect the ending.

Sonic

The main character, using speed and spin attacks to clear stages and manipulate time routes.

Amy Rose

A character who makes her debut in this game and is tied to Sonic’s story.

Metal Sonic

Eggman’s robotic rival, designed to challenge and pursue Sonic.

Dr. Robotnik

The antagonist who tries to exploit Little Planet for his plans.

Use ramps, springs, and long straight sections to build momentum and reach key time posts. If you want a better future in a zone, go to the Past first and destroy the machine or source that creates problems in the present. Time Stones matter more than speed alone if you are aiming for the best ending, so plan routes around them when possible.

Collect all 7 Time Stones to get a better ending.

Collect all Chaos Emeralds to unlock the full completion ending path.
