Mr and Mrs Green is a game in which you were kidnapped by some spies. Their name is Mr and Mrs Green and they locked you inside a house far away from any civilization. You don't know what interest they got to take you, but don't really want to find out. All you want to do now is to escape. You found in the room a key which opens the door, but they will hear that, so you won't manage to get far. What you can try is to distract their attention and keep them in their room for as long, while you could go far away so they won't catch you again. Good luck!
