- Back to: Sonic Advance 3 (prototype; 2004-03-01).
Tag Actions can be used in the Sonic Factory.
When changing Zones in the Sonic Factory, the destination Zone's title card is not displayed on screen.
If the player leaves an Act via the Pause menu or gets a Game Over while holding a Special Key, they will keep the key and they can then use it to enter the Special Stage. In the final, the player must complete the Act to keep the key.
Occasionally a character will become stuck inbetween a piece of level and be unable to escape.
When finishing some levels, the screen will display a blank red screen until the zooming of the text finishes.
The main character's partner will sometimes levitate. At the end of the stages they will start their finishing pose before they even land on the ground.
