From the title I expected the zombies to throw some slander about me, but it turned out to just be normal zombies!
The graphics had a nice style black-and-white fits the zombie theme, making it look like an old movie. The sound could use some variety. More kinds of zombie sounds, maybe some atmospheric music?
The gameplay could also have some variety. Some weapons or powerups maybe, or different zombie kinds.
The use of theme was strightforward, but zombies fit "IT ONLY COMES OUT AT NIGHT" pretty well I guess.
Over all- cool graphics, but the gameplay needs more variety.
