In the house it is quite dark, you need to place house lamps (furniture) and light it with the torch. You can produce furniture in joineries and smitheries, they will make your home look nicer and let you store items. Once the furniture is placed in your house, you can move it by clicking on it with the mouse and placing it somewhere else.
Soon we will add ways to change the (outside) look of your house, add fences to make your own garden, and copy keys so you can share the house with other people (and a way to change the lock of the house in case one of those people goes amok).
