Pac Man is not recording any scores. I did get 79,200 today but hey, it's only a game
BTW - This flash game has a random path sequence for each individual ghost. Therefore it's near impossible to evaluate thier paths or characteristics. Also, the tunnel has no 'safe haven' as in the original game. The Brown ghost will never enter the tunnel from the L/H side besides when the red one is at full speed (or with less than 22 dots remaining).
I expect, once mastered, you could 'entice' the ghosts into running the direction you want them to (or within a quarter of the maze) but nowhere near the original. Cool reproduction though.
