Little Nightmares is an adventure platformer in the style of Limbo and Inside. Much like those games you are cast as a young child who finds themselves in a nightmare world where everything wants to kill them. Unlike those which were strictly 2D this has a 3D element to its linear corridors and passageways.
You play as a little girl named Six who awakens one day in a gigantic submarine type vessel known as The Maw. She decides she is going to escape the huge construct and over the course of the game gradually works her way from the prison area at the bottom all the way upwards to hoped for freedom. Along the way she is hunted by the twisted monstrosities that patrol the rooms of the vessel.
I really loved the idea behind this when I first heard about it, the idea of a strange undersea fortress that kidnaps children seemed really grotesque. Unfortunately this doesn't translate into the game well. Like both Inside and Limbo the story is left a lot of the time up to the player to figure out, it all plays out silently. I knew from the previews this was set in a ship yet the game doesn't do a good job of showing this, each level seems separate from the last and it is only the occasional rocking rooms that remind you where you are. Little Nightmares is split into a variety of levels, each taking place in a different area of The Maw. The prisons patrolled by the long armed janitor, the kitchens where huge hideous chefs prepare food, the Japanese themed dining area where monstrous perpetually hungry guests eat endlessly, and the area where The Maw's owner resides. Each area is made up of a series of rooms that dwarf Six. Whether it is her who is tiny, or the denizens huge it is hard to say, but she is Burrower like having to clamber up bookcases and cupboards to traverse the areas.
