Limbo is like nothing you've played before. You are this kid, that somehow just wakes up in the forest. The graphics are dark and creepy, but in a beautiful way. Backgrounds are magnificent. The sound is exquisite. You then set sail on a journey, which we do not want to spoil. Limbo is a 2D side-scroller with numerous mini puzzles along the way: you will run into traps, huge spiders, creepy habitants, abandoned hotel signs, dams, and for a game that looks so simple, you will suffer some nasty, wicked deaths. Everything, and we do mean everything about this game is exceptional.
