Darkness seems full of frightful potential.
Extremely unique experience.
Failure is boring.
Absurdly punishing consequence for failure in endgame.

Great horror stories are many things, but tedious isn’t on the list, and that’s exactly the feeling that’s born of Knock-Knock’s inability to explain itself. A game that doesn’t tell us how to play and has no consistent rules is a frustrating experience, no matter how eerily beautiful it is. Knock-Knock’s confusing mechanics give little reason to answer the door.62

Whether or not you become frustrated with how the game is played is overshadowed by the fact that you’re probably supposed to feel wary of the events going on in the game. The repetitiveness then becomes the sad tale of insanity in the traditional sense - doing the same thing over and over again and expecting different results.70

Knock-Knock is an interesting experiment in storytelling and mechanics, a title that blends several genres and tries to create a kind of gentle horror that relies more on suggestion than on any sort of sudden scares. Unfortunately, the initial wonder quickly dissipates and the game then fails to offer more interesting ideas to keep gamers occupied.65

Overall this really is not a game I can give a thumbs-up. I’m not entirely sure who’d enjoy a game like this. It’s possible we’ll see a few desperate YouTubers record their girlfriend getting scared by some of the earlier moments in the game, but aside from that tiny bit of stimulation and the initial hope that the nonsensical plot will have a logical finish, there’s very little here for anyone other than the most desperate of horror fans. Sorry Ice Pick.53

Knock-Knock! is definitely something you should check out. It has some of the most gorgeously terrifying designs around, and a crawling, creeping fear to its gameplay that will keep you up at night.70

Knock-Knock is worth experiencing for the horror elements alone: simply to witness how such a simple-looking game can distil such fear in the pit of your stomach. I'm always a connoisseur for something a little bit different in video games, and Knock-Knock is indeed something just that little bit "out there."70

But when it becomes clear that success isn't a matter of overcoming psychological terrors but of discerning rigid, obfuscated logic, Knock-knock reveals itself to be not something horrifying that defies all understanding, but simply a mundane, frustrating little puzzle box.40

They exist within a world where every rule and moral can be accounted for. What Knock-Knock tries to ask us is whether or not these stories, in their pervasive certitude, truly represent reality.70

The gameplay is fun and the anxiety felt even long after the initial shock of what’s happening are maintained by great sound direction and what appears to be a heavily thought out system of randomization. Knock-Knock is highly recommended to all gamers and receives a Perfect 10 out of 10 making it an RGN Diamond Game.100
