something to consider:

"Pac-Man is a game where you wander aimlessly through a maze of dark, featureless corridors, relentlessly chased by the undead. Your combat abilities against them are minimal, and your ammunition extremely limited - there are only four per map. Even if you do "kill" your enemies, they are not truly dead, merely slightly inconvenienced. They can never be truly killed, and live for the sole purpose of hunting you until you're dead.

Do you get what I'm saying? Pac-Man is the first survival horror game."
