Wales Interactive’s Don’t Knock Twice is an “all-in” game if ever there was one. While it can indeed be played without the PSVR headset and during the sunnier daytime hours, the game works best when you wall yourself (Amontillado or not) up all alone in the dark (heh) completely wrapped up in those goofy goggles and a decent set of headphones. Being afraid of the dark and having the additional fear of things that go bump in the night also go a long way in making this mild experience in terror a bit scarier.
On the other hand, if you’re one of those really jaded people who think all horror games need to be gory undead shooting galleries or have stuff jumping out at you every ten seconds, you may not totally grasp what the fuss is all about when the game finally ends somewhere about an hour to hour and a half later. Is the game perfect? Nope. Does it do what it intends to do? Yep. If you let yourself become immersed in the mood it aims for, it’ll get under your skin and make you a bit jumpy for a tiny slice of time. You’re not going to use the (overused) word “innovative” here at all to describe this one. You’re getting a short and creepy horror experience that’s not going to wear out its welcome when all is said and done.
