The second game was on sale today on XBLA arcade, since I never got to play the N64 versions, I bought both.
It's pretty fun so far. You have a ton of moves you can pull off, my favorite so far, is when Kazooie takes over, so you can walk over steep areas, haha. Completed most of the first world, though I'm missing 5 music notes and a couple jigsaw pieces. Not sure where they could be, since I looked all over.
