This week's Steam Midweek Madness is the fantastically simple puzzle-platformer 'Limbo', a dark game about a boy's journey to find his sister in a twisted world of forests, cities and horrible creatures. A quick playthrough of the first five minutes plays whilst I give the low down on what's it's all about, and whether or not it's worth your hard earned cash.
