Plan Game Scene

For my game I have an idea in my head that it will take place in a bedroom in the late 1800's. In the bedroom there will be a cabinet bed folding and unfolding gradually from a bed to a desk. The player will have to collect the pencils around the folding bed. The pencils will increase the players score, but if the player is touched by the bed their score will decrease. 
I think what excites me is that I have my game pretty much planned out already.

My learning topic is science because any invention is science related. My inventor is Sarah Goode. She made the cabinet bed. My game will have the bed opening and closing into the desk, which will be the enemy for the player. There will be pencils to collect while the bed is turned into the desk. If the player is hit by the opening bed they will lose points or die. The pencils will be the points they can earn if they collect them.
