This is cool but there's a bit of a bug when you try to move through the main maze diagonally down-left - the square gets stuck instead of sliding along the wall, which makes moving a bit stickier than it should be.
Also, when going into a castle, the original jumps you into the castle as soon as you move into the open portcullis, whereas in your version you have to keep moving off the top of the screen.
Other than that, great version of the easy mode!
