Has a nice atmosphere
I thought this was a kind of mediocre game. The good parts about it was that it was a bit hard to focus on the gun correctly. I could not even understand the exact place where I should be hitting those zombies. I think it's around the head for one shot kills. I recommend you putting some better design up for the zombies, because they don't seem to move that fluidly. The colors for the most part are good, but some of them seem a bit too flashy.
I find it funny how my partner keeps getting hurt all the time while I'm just fine. The atmosphere created is pretty good, especially with the music. The designs for the main characters aren't bad. I think another weakness was that you should have put in more room for the characters to go around. I guess I'm just not used to zombie shooting games where you don't go and explore.
