It was confusing, at times, but it wasn't that bad. I don't know about challenging though. The only issue I had at times was opening all of the treasure chests, especially the ones in chambers. (stupid heartless, showing up and usually making me fall off :angry Exploration-wise though, I grew to love this level. Why couldn't KH2 have more levels likes this, Wonderland, and Hollow Bastion? You know, levels with a decent amount of explorin' to do. Most of KH2's worlds felt too linear, but KH2 bashing has surely gotten old now, so ehh.
