Finished it last night. I really enjoyed it overall and it was a marvel to look at but I'm not sure I would put it over the other two. "Plot" wise I think I preferred Sotc.
Controls wise, they were pretty bad. The lag in movement and camera rotation is a really weird decision (if by design), but really after a few minutes with the game I could tune myself to it. Controls while on Trico were another thing altogether, and a huge step back from me than Sotc. The auto-hang always tripped me up when wanting to get on/off quickly and I wish I could just hold a button down. Not having a grip gauge is fine just frustrated at this change.
Other than that, fantastic. How the world was laid out in that you could see your goal from the very beginning and where you are headed/where you have been as you progress really pushes all the right buttons for me.
Dealing with Trico wise, I didn't have any major problems or hangups. I had to restart from checkpoint once when he just wanted to sit there and I needed him to pull a chain. Otherwise outside a few jumps in wrong directions I didn't get stuck, or feel as though I couldn't control him. They could cut back on the time "trico thinks for a bit before he does the next thing". Having it there adds to him feeling like a real thing but too much and it starts to become a detriment.
Oh, almost forgot, the barrel puzzles were just not fun either.
