2D Zombie Shooter

Couldn't sleep the other night, so I started working on this and so far it's coming out decent.

Basic Gameplay ( * = already implemented):

-*Destroy zombies to prevent them from reaching the city.
-Certain number of  zombies must be killed per level.
-Cannot allow too many zombies to pass.
-*(So far) Two types of zombies: Normal = 4 shots to kill, Sumo = 10 shots to kill (with pistol).
-Several weapons. Some zombies will drop them. (So far there is a pistol)
-More levels will likely be added as time passes.

The video displays what was accomplished in the first 24 hours of development (though I probably only worked for about 10).

More to come soon.
