The gameplay in Sonic 06 introduced two main characters: Sonic and Princess Elise. The game attempted to blend high-speed platforming, which Sonic is known for, with a more story-driven approach, focusing on the relationship between Sonic and Elise. The controls are responsive, and the speed is there, but the game's physics engine and camera system were criticized for being uncooperative at times. Levels are varied, from traditional Sonic zones to more urban settings like cities.
