Use the arrow keys to move Gus between the three rooms.
The Gus sprite is from @mizzpeters. This is my solution to the #scratchbootcamp Casa Gus challenge. Casa Gus Make a project that creates the illusion of having three separate rooms, in an L shape, with a top-down view (aka plan view). The user should be able to use the arrow keys to move Gus back and forth between the rooms. Gus starts in the center room. When he moves to the top or to the right-hand side of the stage, he should then appear in one of the other rooms.
