Wonderful game with a storyline that keeps you guessing as to what's going on.
It's not a challenging game by any means - the first half of it is easy enough that you can stumble on the solution without actually realizing that you've solved it, until you go into the solution cutscene.
But it has enough character to make up for it, and enough detail that seeing it over and over again is not boring, as you learn more the things you've seen take on new light.
