Gotta say, while everyone is getting excited (or angry) about the obvious new changes, I'm happy for some of the small ones that mostly seem to be going unnoticed as well.
Love the new look of the arenas I've seen so far; I'm not even sure how many more little (or big) things I've walked past without noticing in levels, but the things I've noticed look great!
The game now tells you how many crowns you earned at the end of a run.
