The creator of this remake gave a talk on it at the houston.js meetup this week. I was thoroughly impressed with how much effort and thought he's put into this project. He said that the Pac-Man dossier was his inspiration and seems to genuinely love the game.

For those of you who have criticisms about the game's accuracy, I suggest that you submit a new issue to his github repo: https://github.com/shaunew/Pac-Man/issues. That's what open source is all about, right?
