I recently had an idea for a new category called Half%. It involves doing the following:

-Completing at least 38 levels -Collecting at least 123 star coins -Beating the game.

The run ends upon hitting the hint movie block in peach's castle to show you have 123 star coins or more. It is called Half% because there are 76 levels in the game, and you complete half of them (same with star coins: 246 total, 123 required)

I hope somebody is able to add this category because personally I think this could be interesting.

Idk... It just seems pretty arbitrary because although it would not be the same as other categories it would likely not be that fun to run. The route might be interesting through.
