I would like to know if it is feasible for a minor to create a game.
So... if we say you can't you won't try to do it?

If we say "Sure! It is easy, go for it!" then you will get discouraged and quit when you face the unevitable obstacles and harsh realities of gamemaking and start to think you are not suitable for this. If we say "It is really hard! You have to train zillion years before you can do it!" then you will get discouraged and not even start. All possible answers lead to bad consequences for you
