6.0Overall Don't Knock Twice is quite a hard one to judge. It does what it sets out to do - scare you silly - rather well, and without resorting to cheap jump scares to boot. But with its short length and limited replay value, I'm not sure if it provides value for money. If you're after a new VR experience to enjoy which you'll then scare your friends and family with however, it might just be worth a purchase.
