It is impossible it's a joke where you show it to them on paper, and when they give up you demonstrated how you draw a line from one uttility to the edge of the paper, wrap the line onto the back, punch a hole in the paper and run the line to the last house, otherwise it is impossible

I think this is the guy that developped it, one difference is his has a time limit. Atleast your learning how to make a game, make more levels that are original instead of copying cybercamps, and add something to make it more unique
I don't really know if this is considered stolen... but this is the game they teach you to make in cybercamp in game design course, and I believe that when you sign up to go you sign a form saying that anything you create with their computers they own. In addition, I would have hoped you'd have used more originality than completely compying even the maze that they use in the example.
