Green Hill Zone (Sonic Dash), Sonic Wiki Zone

Green Hill Zone is the fourth Zone that appears in Sonic Dash. Green Hill Zone looks like its 16-bit counterpart, containing totem poles, lots of grass and even 16-bit water. Players are stuck running down a path. They can move left or right (akin the side step). Green Hill Zone has no set goal to reach. The only objective is to keep running for as long as possible. As such, the level cannot be completed in the conventional sense; it only ends when the player switches Zone or gets a game over. A
