Finally out of the editing software,
here's the video of your levels:

I'm not a native speaker of English, but I hope you'll understand most of my comments
I don't really talk that much in the video, but I liked playing all the levels and I think just watching someone else play your levels is useful feedback in itself. IIRC, there were no fatal problems in any of the levels, I just happen to like platforming and action more than puzzles
The first two levels didn't get much airtime I'm afraid, but only because I finished them so quickly. They were fun to play though, definitely following you guys.
Anyone looking for a fun and fair platforming challenge should try Neki's stage, it's easily one of the best user made levels in this style that I've come across yet, really really liked it, check it out:
Rosalina and the Floating Towers
BBB0-0000-0074-53B1
And here's two of my stages if you guys want to give them a go (both include a speed run challenge): 0671-0000-003A-121F + C664-0000-0047-837E
Thanks again for the levels (even you puzzle and semi-puzzle freaks KooopaKid and VandalD), I will definitely do this again, cheers!
