Neo Green Hill Zone
Neo Green Hill Zone is the first zone in Sonic 2 Beta. It is what is now known as Aquatic Ruin Zone. There are no enemies here, except the arrow-shooting totems. The layout is half completed. While the level is certainly playable, one single careless mistake can cost Sonic's life.
Weird splashing animation consisting of misaligned bubbles. Tails has no splashing effects.
Be cautious when underwater. The pits are very shallow and you'd be killed if fall into one of them.
Miss this swinging platform and Sonic is history as he falls all the way out of the edge of the screen.
