Limbo is just an empty space, there are no walls, ceiling or even any floor. However there is Death's very own Casino where you can gamble to win your life back.
Being that there is no walls etc, it is difficult to design such a space but this is the kind of thing I'm looking for. Colour is a key element for my environment so I tried to avoid black as much as possible in these initial thumbnails.
