The level is very well decorated, contains a lot of good mechanics (I know many of them, such as the death trap, platform trampoline and the "press P twice" trick), good length and a pretty satisfying difficulty. I do agree with other people that the story isn't the highlight of this level, but I still think the idea is quite interesting.
I am not very skill with SM63 so I tend to finish the level with a bit of cheating (this level is no exception
All in all, I don't think I have any reason not to give it 5 out of 5, RESPECT!
