About Sonic and Knuckles

Sonic and Knuckles brings Genesis-era Sonic action to your browser — rings as your lifeline, loops and springs as your rhythm section, and level routes stacked vertically so the fast path is always the one you haven't found yet.

It's played with keyboard and mouse, so there's no setup beyond your hands and the screen. Short sessions work fine; long ones happen anyway.
