It would be cool if there was speedruns for the individual color sections

This is kind of random but you beat the game while using the least amount of clear pipes as possible.

Basically you have to beat the game with using cappy as little as possible. This includes even throwing him. I know it probably is a bad idea but I think it sounds cool and challenging.

It would be awesome if you could speedrun individual levels

You just have to get the first cat shine as fast as possible.

There should be a category for Bowser's fury multiplayer. Maybe it could be a category extension?

I had an idea for a Bowser's Fury category extension. You have to beat the tutorial and talk to Bowser Jr as fast as possible. I feel like they should already have a category like this, but I think it will be a cool idea. It could also be a good way to practice for the beginning of any%
