Bought it this morning and finished it. I enjoyed it even though the control scheme kept fucking with my head. I don't think I ever really got used to controlling each character independently. Strangely enough, I seemed to have the most difficulty when there wasn't much going on and I was guiding them down the path. I'd inevitably get them mixed up......I suppose my brain isn't able to do this kind of multitasking.
There's one section in the game when you're scaling a dilapidated bridge and tower that totally gave me ICO flashbacks. I guess we finally got that next gen ico game.....thanks Starbreeze. There was another cool moment near the end of the game that reinforced the relationship between the two brothers that was actually thoughtful in its execution. I was kind of expecting the story to unfold the way it did but they really nailed the character's growth in that scene.
Kind of a cool little game.
