I almost called it quits on the part with the diving, too. I'm glad I'm not the only one that had trouble with that.
That aside, I really did enjoy the game, if for no other reason than I knew what I was signing up for when you have a young kid and a giant pet - lots of patience, frustration, miscommunication, but rewarding when you feel like the AI lined up with what you had in mind.
I do think a lot of patience is needed to play through it proficiently, observing and waiting to see what Trico thinks and does in a situation. The 'diving' part can screw right off, though.
Edit: ALSO I dunno if anyone else had this issue but I had a big problem with mashing every button on my controller every time a guard caught me - I always had that lingering feeling that it was contributing to that day when my controller would break. That's a terrible system that's the opposite of innovative. "Just mash ALL THE BUTTONS AT ONCE to break free! It's that simple!"
