I am really enjoying the game so far, but any chance to add more zombies/or increase the zombie spawn rate?

So far its pretty easy to survive, and zombies basically feel like no threat. Or maybe i just have not gotten to a part of the map yet where there is 50+ zombies after you :)

Edit: totally missed the spawn count multiplayer in the opening settings! will def have to try this further than just x 1!

There is a spawn count multiplier in the settings.
