11/10/2021 Game Update

Made some balance changes to make the game a bit more fair and challenging. The maximum ammo count that the player can carry at one time has been increased, but the starting ammo count remains the same. This helps eliminate situations where the finite amount of ammo on the map is wasted when the player picks up an ammo pack while close to the maximum amount of ammo. Zombie speed has been slightly increased to add a bit more challenge while fighting them.
