Presto Studios, Ubisoft.
The 360 views introduced in this game were really a step up in the immersion factor and a good choice, and rewarding each world with a rollercoaster ride was a good idea. I don't find the actual puzzles memorable, nor did everything feel as connected as it had in Riven. I particularly remember getting super stuck at one point because of a scene where I didn't notice an exit (something where you were standing on a tree branch and you could move to another branch?) That wasn't a great feeling.
