Green Hill Zone is the iconic starting point of Sonic's adventure, characterized by its lush green landscapes, palm trees, and checkerboard patterns. It serves as an excellent introduction to the game's mechanics, featuring plenty of loops, springs, and basic enemies. Focus on maintaining momentum and collecting rings.
There are three Acts in Green Hill Zone, each culminating in a goal post or a boss fight. Pay attention to the various pathways; often, higher paths lead to more rings and fewer enemies, while lower paths might contain hidden power-ups or shortcuts. Practice your Spin Dash here to get comfortable with its timing and power, as it will be essential for later zones.
