Blocks that land in lava now bob up and down in REV01. There is a suggestion this was always the intended behaviour, as this motion occurs in prototype versions of the game.

Parallax scrolling has also been added to Spring Yard Zone's background. Previously it was entirely static.

There is an obscure shortcut in Labyrinth Zone Act 1; if Sonic presses the left button in the second underwater section (the one with the two rising platforms), a secret moving platform will spawn above. If the player can backtrack up to the surface, the top path of the level can be accessed.

It is on this route that REV01 adds an extra Ring, making it possible to collect 50 Rings and access the Special Stage while taking this shortcut.

Scrap Brain Zone Act 1 also gets parallax scrolling.
