The backgrounds of Hill Top and Chemical Plant don't move.If Sonic and Tails are hit at the same time, lots of rings will sprawl out regardless of how many rings they actually have (provided the player has at least one ring).If Tails dies, the camera will follow him as he respawns until he goes off-screen.Tails can lose rings for the player if he is hurt.Each Zone uses music from the original Sonic the Hedgehog.Sonic and Tails are in different symmetrical designs on the end signpost.This feature was scrapped sometime after this build, but the sprites it uses are still present in the Simon Wai prototype.
