Beautiful game. It does a lot better than ICO, but I think ICO was more consistent. Most of the puzzles are relatively easy to wrap your head around, but the controls can get in the way, on top of general ambiguity on when/where to grab some of the colossi. My main two sticking points are trying to grab the tail of the 7th colossus, and the hand of the 15th. That being said, it is an incredible experience, and you can feel it's DNA in many games since.
