What is your favorite main feature in a Revomaze puzzle?

[prodigy]

I am just curious what you think is your favorite main feature in a Revomaze puzzle (and we don't mention what the main features are, just what we think of them)? I can only choose 10 different mazes to the vote so therefor are not all different features represented. I think these are top ten different mazes with different main features. You can choose three favorites.

Just reached the second part of the bronze maze after 19 hours of puzzling. Great feeling after loads of frustration.
(but who knows what my orange or silver will bring me)

I like the spinny bit
