Sonic CD

Race across a strange world packed with broken time in Sonic CD, a fast side-scrolling Sonic game built around time stones and classic ring chasing. Dr. Eggman has locked these stones on a distant planet and wants to twist time itself to his plans. Sonic heads there, runs into Amy Rose, then Metal Sonic grabs her right in front of him. From that moment, you push forward to reach the stones first, beat Eggman's machines, and bring Amy back.

How to play?

The planet is split into seven big stages called rounds, and each round has three zones with its own layout and enemy placements. Robot opponents called badniks patrol these paths. They block springs, ramps, and narrow spaces Sonic needs to cross, so you can't just ignore them. Curl into a spinning ball and hit them at high speed to break their shells. When a badnik bursts, a small creature escapes and a flower appears in its place, showing that spot is freed from Eggman's tech. Metal Sonic stays in the background of the story, while Eggman's robots keep trying to slow your progress toward the time stones. Collect the glowing stones as you advance to shut down his plan to control time.
