South island is a beautiful place with its Green Hills. This is not related to Green Hill Fall zone, other than location.
I have started development on Sonic the Hedgehog: World Tour, the game I made this for. I used Emerald Hill assets in this because the Sonic 1 manga had hills that look like the Emerald Hill hills in the background. Act 2 will be based on the TTS prototype background, with the rocky waterfall area being more blocky.
