Use the arrow keys to move the helicopter. Land it on the landing pad to complete the mission. You can start it again to get another mission. There is a real helicopter that went to mars! Every time you do it again the background changes. Have fun!
There was a video that gave some things to do if you want to follow that. It was not on scratch though. Just search Mars helicopter code and you can make one just like mine. Or you can remix it. Whatever you want. You don't even have to do it. It was just a suggestion.
