Sep 13, 2015Knock Knock isn't quite a nightmare, but with a little more focus, it could have been a dream to play.

Sep 14, 2015Knock-Knock is a game with great sound work, a nice, unsettling art style, but several flaws. Its mechanics are never explained. You can expect to replay the entire thing over again to see its “best” and “good” endings.

Sep 15, 2015I love the atmosphere within Knock-Knock, the art direction works really well, and the descent into madness idea has potential. I just found myself not wanting to play anymore about four cycles into the game.

Sep 27, 2015As it stands it’s a bit of a mess.
