Not sure how long the game is....or even if its endless like the walls within the maze, but i got to lvl 11 and it took me quite a while. It was a great experience though, where as I walked further and looped more often, I was increasingly scratching my head trying to find some kind of pattern. Upon reaching lvl 11, I figure I've done enough brain blasting for one sitting and will throw in the white flag (for now). Great game! Would definitely play again to challenge myself further!
