This game is unique. But that's not necessarily a good thing. Its story, gameplay and visuals all bring some novelty to the table but that couldn't save it from getting boring after about an hour of play.
The problem is that the puzzles never evolve past what you see from the start of the game. They are also unpleasantly inconsistent in difficulty.
There are some fascinating ideas presented in the universe this game places you in. But again, the narrative frequently lost me by being too mysterious and lacking in any characters worth caring about.
This review isn't a resounding "No, don't play it!" Instead I'd just caution you to not get caught up in all the high soaring reviews this game has received unless you are the type of person that can't get enough of 2D platform puzzlers filled with mystery and ambience.
