Doesn't have the perfect momentum of the first, most of the dialogues halt the gameplay to a T, but it's still fun. It gets rid of the platform stages of the first and adds physics puzzles. In this one i feel like valve was afraid of the player getting bored, all of the chapters add an unique novelty. Not a fan of how gray everything looks and i feel like the physic puzzle have not aged the best but it's still original and fun to this day.
