Pac-Man, the quintessential classic arcade game, was originally created by Namco in the early 80's and has now been updated for the web.
The idea is a simple one - guide Pac-Man around the maze and eat all the little white dots whilst avoiding those nasty ghosts. If you eat a Power Pill, you can eat the ghosts! Occasionally, a fruit appears which gives you a bonus score when eaten.
Arrow keys move PacMan. P will pause/unpause. Q will quit. M will mute/unmute sound. L will lower/higher quality.
