The maze is too easy. Click on "See inside" (blue button up above) and then click on the orange "Remix" button and finish the maze. You'll also need to add some more scripts to make sure everything works correctly (check the comments). Lastly, you need to make a "finish" to the maze. Something that lets the user know they've completed it.
For bonus points, you can make it a game by adding a timer, or counting how many times the user touched the wall or something to that effect.
