In this game, all this master key in only one image: That which you have at the beginning. All is has to discover, including what you must do! And it is very funny... Therefore, as you do not have any idee at the beginning, to test all and anything. Certain things are interactive. To click above, look at what it occurs. Look at all the details well because they are significant (for example: all the objects are not the same ones in the gun!). To change the order in which you make the things, because Ca can give different results. In short, amuse until A what you include/understand what you must make and how!
