I had written a fairly in-depth review, but it somehow got lost in the ether. Suffice it to say that the story is very lacking without getting the companion app (and then "logging in" to the locked section of the same app after your first play through), and the puzzles are banal at best, me having to take a large amount of screenshots just for the sequences. Also, the map shouldnt have been made the way it was, both for being very confusing and maze-like, and for having inconsistencies that, excepting that we are to assume that the player can jump through the fourth dimension, would have it intersecting itself badly if the lengths of the paths are consistent.
After just finishing my first play through of Device 6 (a game that I was extremely pleased with), this game came as a serious disappointment.
All that being said, the entire game (companion app included) lent itself a very pleasingly creepy atmosphere that I enjoyed regardless of everything else. There was one jump scare that had me turning my device away from my face through my second play through to spare myself an early death by heart attack. None of the other jump scares were very effective.
I know there are people out there that would definitely enjoy this game very much, so if my review doesnt turn you off to it and you like what you are seeing in other reviews, then by all means get the game. However, I know there are others that will share my thoughts and I hope that this review will help keep those people from wasting four dollars.
