Awesome puzzle game! Short in terms of gameplay time (3 to 6) hours, depending. I loved the story and it is a beautiful game with ray tracing. Soundtrack is good! If you read/listen/watch everything within the game, you'll get the real feel of the game. You are the last hope! 100% recommended if you love puzzle games. You will get kind of frustrated in some areas, the game doesn't tell you that much, you need to figure almost everything out by yourself, just a few clues here and there... but not impossible... challenging at times. Ending was good with a mid credits scene. 5 stars for me!
