Genius idea! A couple of suggestion for improvements: I would make the wall neon color change (from blue to yellow, for example) when pac-man is under effect of the super-pill.
Also I think it would be so cool to have "windows" in the walls through which the player could see ghosts in the adjacent corridors and move accordingly. I think it would add an extra strategy level when it comes to decide which way to turn at a crossroad!
Hey thanks Francesco!
