The HUD timer uses a colon to separate the minute from the seconds, unlike the final which uses prime marks.

The Grand Prix and Time Trial modes (as well as the monitor options) do not exist as a result of a lack of a menu for the mode.

There are still some things that were changed, however:

The Competition Mode levels are overall more complete than the single-player ones and even feature the final game's player sprites.

Objects that Sonic can hang onto still act like Wing Fortress' from Sonic 2, in that Sonic won't curl into a ball when jumping off, and his animation stays the same.

Many stage transitions have not been properly implemented yet, so the Level Select is required to continue to the next Zone in most cases.

The 'animation test' accessed by pressing B + C in Debug Mode has not been implemented.Super Sonic has been partially implemented and has the ability to shoot rings, which was removed from the final.Tails cannot get tired from flying or swimming.Tails cannot change his flight direction if jumping from a curve-pipe.

Tails' flight ability is incomplete, and every jump press will result in maximum levitation, regardless of drop speed.Tails will fly instead of swimming when attempting to fly underwater and is also capable of carrying Sonic underwater.It's very easy to clip into walls due to unfinished collision.Even though sparkles appear above checkpoints when Sonic has 50 rings, the Bonus Stages are inaccessible through normal play.The Insta-Shield isn't implemented yet.Special Stage rings aren't present, though all their respective locations are.Elemental shields lack their specific effects.The move is remarkably similar to the Drop Dash of Sonic Mania, which Christian Whitehead confirmed was a coincidence. Sonic and Knuckles are also able to use this ability in Competition Mode. Jumping while holding Up will cause Sonic to do a quick roll forward after landing.
