I don't think so. I'd have liked it if they had added more moments where you had to create new portals mid air in order to continue your jump. I remember a ton of times I had to do this in portal 1 and hardly any in portal 2. Almost everything was set up so you could do it with 2 (4 in coop) portals. It feels like they changed it to be more suitable for console play.
Like I said, I enjoyed the game. But I was hoping for some more challenging situations.
In any case... I want to 100% the game, so is there anyone who hasn't played coop who wants to help me get professor portal achievement? I'm playing on PC.
