I liked the puzzles a lot, usually not too challenging or too easy, but time to time their difficulty changes, and that helps the pace of the game. I liked the story in the background, all that philosophical texts. I think they're very interesting as a reward for progress. But over time because of the lack of a sound main story, the game starts to become less interesting. You just start to say "this is what I'll be doing for next hours" and not get curious anymore. Overall it's a great puzzle game with texts that might make you question many things about life and humanity.
It's smaller than the the last games but has a great story and the gameplay is still creative.
