From the developer:
WorldCraft is a sandbox game in which you need to learn how to mine and craft new things, live in the dark night, and fight with zombies and monsters. You can also build amazing buildings, gardens or anything you like. Monsters and zombies will spawn around and try to kill you. You can use your swords and any weapons to fight with those creatures.
