I'm giving this 5/5 because I'm pretty sure the maps I had huge problems with are much better if you're expecting above skill 0.
Highlights for me were iYago's combination of atmosphere and little setpiece challenges (I particularly liked the setup for the room with the knights), Magnetbox's perfectly flowing design with runic styling, and Atomik's which just sat well with me. I did like the Giant Coils in mtsch's map as well, as a stylistic thing.
If I were to nitpick, Spootnik and Colossus' maps felt too hard for me on skill 0 - and I think part of the problem is the short duration of the "mini-powerups" imposing its own limit of how easy you can make the challenge setpieces - although I also felt that the "water tunnels" bit in Spoot's finale was super hard to accomplish for me. (At least two of Colossus' bits I god-moded through - but with "full-length" or even half-length rather than mini- powerups, I think I would have found them enjoyable without being super hard.) I also managed to die about 10 times in the start map, but I don't hold my lack of jumping ability against it!
If you are not bad at jumping and are good at aiming fast at things, you probably won't have the same issues...
