You unzip the folder by right clicking it and extracting it. you should find an exe file in the extracted folder. double click that to run the game. If you get a protection error click more information and click run anyway.
If you find that fun, you will probably enjoy putting a small object (i.e the phone) under a large object (i.e the digger) and then jumping on said large object grabbing small object then flying. takes a few tries kinda fun.
