About Sonic 2 Reversed Frequencies
I first played Sonic 2 Reversed Frequencies on the Sega Genesis, a modified version of the original Sonic the Hedgehog 2 released by Sega. It was a time when players were finding new ways to experience familiar games, and this hack fit right into that experimental phase on the 16-bit system.
You control Sonic, and your goal is still to stop Dr. Robotnik, but the entire game is flipped horizontally. This mirroring changes every level's layout, forcing you to relearn the pathways and enemy placements you might have memorized. The pacing feels different, almost unfamiliar, as you navigate reversed loops and jumps that demand new timing. It's a strange, disorienting experience that makes a classic game feel surprisingly fresh again.
