Excellent game, the puzzles are balanced just right, and the storyline is original and quite deep (you'll often find yourself looking up stuff on Google that the characters talk about, like the Sleeping Beauty paradox, for example). Animation isn't great, but this really doesn't matter at all in this type of game. If you want a mix between a story-driven game and a puzzle game, and you like Japanese sci-fi, then go for it. Excellent music too.
