Oh, by the way, cool announcement.
My last level will not be a level. Considering it'd be all dialogue, I am going to be making a short film out of Super Mario 63 that will showcase the prologue. There will be next to no new elements otherwise-the entire 3rd level will take place with the layout of the 1st. Plus I can add neat elements like background change and soundtrack outside of Super Mario 63's limitations. (How do you like How To Train Your Dragon scores?

)
So yeah, new element. This is more of a innovative thing than a score thing. I doubt I'll get more than an extra point or two for this.
Cheers!
