This is a starting point for other people. No permission is required to edit my map as long as you give credits to me(Daxter3005) later.
The units go to sleep at 6pm(18.00) and wake up at 6am(06.00) but at 23.00(11pm), zombies, skeletons, ghouls, all these random undead will spawn and wander the streets, but they will fade away when the sun comes out again.
You don't have control of anything but you can type lightsout to make it night or riseandshine to make it morning.
Try clicking the chickens too.
