A mega mushroom nor a starman can be collected when playing alone, it is necessary to be atleast 2. And the rules state that you need to play in solo, making some runs just impossible.
Also, being able to choose "any" map in the speedruns makes no sense as it will only duplicate one of the maps' leaderboard
Lastly, I would like to suggest a new category, Annihilate%, which combines Crushing all blocks% and Killing ennemies% (if you take a star, and block respawn, that means that you gotta redo it all over again)
I have more to add ^^' There's a mistake in Killing ennemies% Some ennemies are not on all maps, the most obvious example is the Pirhanna plant, which there are none on Grassland for exemple And there are more ennemies that just these ennemies: spinies, bullet bills, blue koopa, bob-bomb
