Sleepless Night 2: Ladies' Night(mare)

This freeware game sounds interesting and described by the game author as this. "Sleepless Night 2: Ladies’ Night(mare) is a horror/psycho sound novel. For full game experience you should play at night alone in your room and turn the volume up. There are no 18+ scenes in the game, I would recommend the game for 16+, but it is very scary and there are a lot of shockers in it, so be warned!" There is a walkthrough (spoilers) for the game. Downloads for Windows, Linux and Mac.
