Celestial Heights

You're a construction worker who has been in charge of demolishing an unfinished skyscraper project that went wrong. Everything is all set up for blowing up the building but then you realize you forgot your lunch all the way on top of it. You are very hungry so you better hurry up and grab your grappling hook so that you can reach your precious lunch before the building completely collapses.
