You dont see games like this a lot. Its very fun, challenging at times, and really requires you to use your head. Sometimes its about finding patterns in what seems like random things, and sometimes its about observing until you know exactly what to do. Its very reminiscent of 2001: A Space Odyssey, especially the level "Path" which looks exactly like the Stargate sequence in 2001. I see a lot of people complaining about the "lack of story" and it really isnt that type of game that tells you exactly what the story is, you come up with your own story as you progress. You could imagine that you were on a space mission and somehow got lost in another dimension, you could imagine that Earth has become inhospitable, and you are trying to find a new planet to survive on, the possibilities are endless, which is whats awesome. It is kind of short, but you can replay it, and create a whole new story. Id love if they added new chapters, but there is nothing wrong with how it is now. All in all, its an amazing game.
