ooooh! I see. I think the game isnt clear enough for the player to understand which one is the door to go outside and stuff. I am so sorry for that haha ðŸ˜. The door to go outside is the one on the right of the middle door.
I think you picked the gameboy by clicking on the desk right after the desk is signaled for game which is when you are going back into the bedroom. It is supossed that you go outside and then go back into the bedroom xd
