Click mouse to zombie 2d to smash :)

It is a great option for stress busting and also to test your reflexes. A hoard of zombies is after normal people. Your job is to tap and smash as many of them as possible before they disappear across the screen. Be careful of the normal people though, smashing them will only lead to your game being over and making the job of zombies easy. It is a great app to pass your free time as well as have fun while doing so
