Yes, it exists, currently up to the end of World 2. Something to note with the modded version, not sure if it's the same with the actual game...
When you first start it up, it will appear to fail to load. DO NOT DO ANYTHING. If you don't let it load this first time, when you boot it up next, it will be on an infinite loading screen. After a few minutes, the game will boot up with no problems.
