Sunset Hill is the second zone, characterized by its vibrant, natural landscapes and ancient ruins. This zone introduces more complex platforming elements, including moving platforms, crumbling structures, and water sections. The beautiful scenery belies some tricky challenges, requiring precise jumps and effective use of your partner's abilities.

You'll find many opportunities for vertical exploration and hidden paths. Characters like Tails and Knuckles become particularly useful here for reaching high ledges or gliding over dangerous gaps. Keep an eye out for the ancient ruins, as they often contain secrets or lead to alternative routes. The zone's aesthetic is reminiscent of classic Sonic levels, providing a nostalgic yet fresh experience.
