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.
