Very proud to say I got through the game without a walkthrough. Better than the first game in almost every way, really great immersive environmental storytelling. Puzzles are pretty tough to figure out, and they're all interconnected and you gotta pay a lot of attention to every little thing in the game world and write stuff down. Story is very good too, if you played the first game (and if you like reading nearly illegible in-game books). Super cool game - I like
