About

A fast-paced platformer that follows Sonic as he races through time-traveling zones to rescue past and future versions of stages and stop Dr. Robotnik’s time-altering plans. Combining classic Sonic speed and precision with CD-quality music, animated cutscenes, and branching time-based routes, it rewards quick reflexes and exploration to unlock true endings.
