Needs an update:

The nights are way too long, and the days are way too short, I think that this is probably the best survival out there so far, but another thing, I tried to pick off a zombie from a distance at a house, so he died, but right away he came back over and over again, itd be really awesome if the next update fixed how zombies would come right back and balance the day/night cycle THX
