Run! Jump! file

You were kidnapped and put inside a building that is falling apart and has no door and the only way out is the exit at the top of the tall building. The building seems to be an old labratory that has an anti gravity gun. materials that were in the building have been shot with the gun and are floating already. Now all you need to do is get out of the building and just maybe find someone who can help you. Now I must leave you with three words JUST DON'T FALL!
