Here you are, at the final depth. Danger lurks behind every corner, even the Shadow People are afraid of this place. Will you be able to get back to the surface and wake up? Or will you remain here forever? The last part of the Deep Sleep trilogy. For the best gaming experience, use headphones and turn off the lights. It is recommended to play the previous 2 games if you haven't seen them before - links are in game's main menu.
