In this earlier build of Sonic 2, we have clear evidence that it was built off of Sonic 1. That evidence is in the form of this zone! The leftovers of green hill zone are more than complete in this build, they actually went to the trouble of converting the 256x256 tiles down to 128x128.
Welcome to Green Hill Zone! However this isn't as cool as it looks, as you can probably tell from the garbled lives icon and hud. Just try walking! |
The collision data in this level is significantly damaged, enough to make walking very difficult indeed, however you can jump and run to get around it to an extent. |
 
Comparing the prototype version with the Sonic 1 version, we can see the item boxes have had mappings changes. |
