Sonic the Hedgehog – Special Stage
A 3D animated scene featuring Sonic, Tails, Knuckles, Amy, Metal Sonic, and Dr. Robotnik in a Special Stage. The design is based on the pseudo-3D Special Stages of Sonic CD.
You can freely choose the music that plays (including shuffling all of it), toggle the clock, and toggle the audiovisual effect. The camera has both dynamic and static options.
There’s also an optional "90’s Mode" that will give the screen a retro TV filter. Try clicking on Sonic and his friends, too!
