The remakes look really good -- good job! Does the original Pac-Man remake use the same AI behavior as the original arcade version? I ask because I tried using the "safe spot" trick (src: http://strategywiki.org/wiki/Pac-Man/Tips#The_safe_spot http://strategywiki.org/wiki/Pac-Man/Tips#The_safe_spot ) and the red ghost caught me every time.

It looks like there was an attempt to copy at least some of the original AI behavior. If you click on the "Learn" tab, you can choose which ghost to play and visually see their AI objectives via a little node that travels infront of the ghost's body. As you probably know, each ghost had their own AI objective and behavior in the original arcade Pac-Man. While their movement's appeared random, they were actually not, and you could exploit each ghost's "weakness" to win.

  I could of swore in the original Pacman the blue ghost will flee when confronted and there's a path for him to escape into.. Which would explain "Bashful"s name (and Japanese name which translates to Fickle).

    Only if red Shadow is behind pac-man. Bashful targets the location (pacman + (pacman - shadow))

It didn't seem to work. I'm not a Pac-Man expert, but the ghost behavior didn't feel the same to me here as it does on an emulated version of the original. (I liked the speed though, Pac-Man is too slow.)

  The hiding spot doesn't work, so there is definitely something amiss with the behavior. Still very fun.

The AI's out there apparently. I've heard Marcin Wichary, explain that he reproduced the AI in JavaScript when he built the Google doodle. I think it's in this video: http://www.youtube.com/watch?v=ttavBa4giPc http://www.youtube.com/watch?v=ttavBa4giPc

The safe spot works for me. The safe spot exploits the fact that ghosts are not allowed to turn upwards in the corridor immediately below the safe spot [1]. That behavior was accurately emulated in this version. Make sure the red ghost passes below your safe spot from right to left. It wants to turn upwards, but it is not allowed to, so it has to keep going. It then circles around back in a T shape. Make sure you are facing upwards, so that the blue ghost circles the center of the maze. Finally, be mindful of the scatter phases [2]. A scatter phase will bring the red ghost out of his loop, so you need to lure him back into it. After the final scatter phase you can stay in the safe spot indefinitely.

I've been receiving complaints about this from multiple people. To my knowledge, the safe spot only works because the ghosts can't go up from the passage below it. It's hard to isolate this bug unless I get a play-by-play or video to compare with the original.

I've uploaded a fix, so it's working now. Thanks for the feedback.
