Cool idea, I am bit worried about the office safety in this game. Hope they have good insurance policy.
At first the shooting mechanics were confusing as I thought that the gun fires by it self, but no it was just delayed and my tiny brain couldn't comprehend it. After getting through the mental blockage the game opened up a bit.
With more polish and attention to the shooting mechanics I think this could be something very enjoyable.
P.S. I wish I had a lawn mower.
