There is a paid version

For all of you that think this is stupid and the guy is just trying to money you are wrong. There is a paid version which gives you more to the game and no more ads. I do agree that there should not be an ad when the fuel bar is loading and it makes you fail the mission. So everyone who says that the creator is just trying to make a quick buck from the ads, you can stop because you are wrong.
