A few additions were made. As you may already be aware, there are certain sounds as well as larger zombies that have some health. For them to be killed, it takes more than one shot. A score counter that keeps track of how many zombies you killed is also included, together with the addition of blood that appears every time you kill them. The score will now be shown alongside the amount of time you survived on the game over screen.

Play testing showed no issues. Testers recommended the big zombies should die with 5 hits so I lowered their health.
