I thought this was great fun!
I liked the art style and the moving/shooting. The clouds gave it a nice feel.
My only niggles were that Zombies look like they need to be slightly closer before they should kill you (looked like it worked on some kind of collision detection? Which didn't feel right if you hit a zombie above you in my opinion) Otherwise all it's missing is a good chip tune to play along with it :)
