- Back to: Sonic Rush (E3 demo).
General comparisons
The title screen is different and features purple and blue zigzags that scroll across the top of the screen. In the final, the entire screen scrolls. The copyright information also uses a different font and reads "© 2005,SEGA" instead of "© SEGA Corporation, 2005".
Gameplay comparisons
The player is able to Boost in mid-air. This ability would be restored in the Nintendo DS version of Sonic Colours, which uses the same engine as Sonic Rush.
The Tension Gauge refills itself automatically when running, albeit slowly.
The "infinite boost" state when the Tension Gauge is maxed out is not implemented yet. The Tension Gauge will flash, but boosting will still drain it like normal.
Enemies don't go flying when boosted into - they simply explode on the spot.
The Jump Dash and Homing Attack are mapped to the 
and 
buttons (the same buttons used for jumping) in this demo, whereas the final maps the moves to the 
button. There are also no afterimages when using the Homing Attack.
There is no point decay for repeatedly performing Trick Actions on the same object/gimmick, making it much easier to get a high score.
Collecting 100 Rings doesn't award an extra life.
The game cannot be paused.
After clearing Leaf Storm or playing for a certain amount of time, the game displays a "Coming Soon" screen. This screen is also displayed instead of a Game Over when the player runs out of lives.
Graphics comparisons
The software icon for the E3 demo has an unfinished highlight in Sonic's left eye.
Title cards have numerous small differences from the final:
- No Act number is displayed, likely due to the demo only featuring one Act.
- The Sonic head is different, resembling the Sonic Team logo.
- The icon used to represent Leaf Storm is slightly different, depicting a larger tree.
- The shading/highlight on the left banner is inverted.
- The font for "On Your Mark" and "Ready?" is slightly more condensed and has a thinner outline.
Sonic has a different animation when looking upwards, resembling the animation for the same action in the Sonic Advance games.
The life icon is slightly smaller than in the final, and Sonic's eyes are looking in a different direction.
The results screen is different in this build and uses the number sprites from Sonic Advance 3. Sonic is also slightly off-centered.
Audio comparisons
Much of the music in this demo is entirely different from the final. It is composed by Teruhiko Nakagawa and is similar in style to the Sonic Advance games, as opposed to Hideki Naganuma's soundtrack in the final game.

The voice work of Ryan Drummond is used instead of Jason Griffith, recycled from Sonic Advance 3.
The E3 ROM uses a single .sdat for the music, while in the final, multiple .sdat files were used.
Level comparisons
Localisation comparisons
The E3 demo will change its language based on the system's language, though only between English and Japanese. The final adds support for more languages.
The "Coming Soon" screen is a bit more descriptive in Japanese.
