About this game

The player lives alone in a house which he must protect to survive. In order to protect his home the player needs to get out of his house and collect resources by picking any location on the map, different places give different resources but the player should be aware that every visit costs valuable time, therefore the player needs to plan ahead in order to survive the nights. While it’s night zombies are outside the player's house so he can’t get any more resources and the player needs to repair all his windows to defend himself against the undead masses lurking outside.
