The first half has some nice theming. It's pretty simple, with a dark atmosphere, unintrusive block designs and the most notable decoration being the crosswalk symbols flashing at the bottom. The second half takes all that and shatters it, favoring instead bright reds, yellows and greens and generally messy designs. It even contains the Deadlocked bossfight in one part. Overall, I'd say it's a great experience. Just make sure to practice it first. Especially the ending. You'll need it.
