It was good...
With some more time this game could have been much better. In this case you are a newer artist so I cut you some slack. I look forward to seeing some more of your submissions.
Graphics- Not too great in this area but it was handrawn therefore original, 4.
Style- Alot like Doom huh? An okay rendering of a FPS.
Sound- Good quality sound, though you could have changed the music for some dramatization
Violence- Zombies + FPS = Violence duh
Interactivity- With me its either a 0 or a 10... It was interactive hence the 10.
Humor- Wasn't funny at all...
P.S. What's with the pentagram on the boss's head?... I thought they were infected... The pentagram isn't really even a satanic symbol, it's a symbolic reference to The Divine Goddess... A Pagan nature goddess...
