Awesome, however...
It needs a little work. It's addicting and super fun to play. However, it's pointless. It's fun but that's all it has. Destroying the zombies has no challenge, you just drive your fist through them or kick them. It's also a bit easy.
However, I like the office theme and it gets addicting quickly, so you're having fun the moment you start playing the game. And the graphics and animation were good. I enjoy playing this no matter how pointless it is!
10/10! It's great!
