it is called jm_skys - It has 3 skyscrapers in it
You start off with an invisible maze, then going onto the second skyscraper where there are some little jumps,
then Doin a 400 unit jump but that building is lower down,
Then go down the side of the building, through an opening you then have to go back up the Skyscraper but inside, where there are a number of things, you then walk along all the skyscrapers, to do a few jumps, and then go inside the first one go up some ladders then Down a Target Tube where u fall from the top of the scraper right to the bottom,
Also when you are inside the 3rd building there is the Grind Bar

Post if any problems,
Here are the links,
