Don't Knock Twice doesn't offer much more that would constitute any sort of positive reinforcement for picking this up for any reason what so ever, which is sad, as a good 'scare game' is something that can be fun, as Halloween is approaching. Even at the admission price of $9.99, it's unfortunate that I would have to say you should avoid this game entirely. It suffers tremendously from numerous faults and setbacks that prohibit a truly horrific experience. Regrettably, the only positive that I can see is that the game does offer a lot of easy achievements to obtain, so if you want a "cheevo" boost then this might be for you. Games based on movies never tend to work well, and unfortunately Don't Knock Twice is yet another example of why titles like these should be avoided. Forget knocking twice, just don't knock at all and go play something else.
