Wow this game is A-maze-ing !
I absolutely love the concept. First I thought that it was similar to a "classic maze game" ... and then the second level introduced a second "player" and I realized the great potential of your game. Adding multiple orange players and adding borders were great ideas.
I wonder how did you level-designed it ? Did you draw a "random" maze and adjuste it with multiple tests or did you find a technique to design good mazes ?
I had a lot of fun : Very Nice job !
