What if there was a category where you complete exactly 10% of the game. (9 different exits, secret exits count as different exits, and 25 different Star coins) Timing would start the same as any% and end once you get your 25th star coin or your 9th exit

Weird idea. I wouldn't accept

this idea would be in a more favorable position if there was like a % marker in the game or something but yea is kinda random purposed like this

I don’t really think a percent marker is necessary because you know how many levels and Star coins you need to beat 10% of the game

I mean why not do this category even if many players won't run it. We have coinless who only 2 people have done so why not this one?

Comparing this to coinless is not a fair comparison. Coinless is a part of the leaderboard to give recognition to the players who have put in many hours to complete the absurdly difficult challenge while also attempting to be fast. This is a category that almost anyone could complete with minimal preparation. If this category has little to no interest, there's no point in having an almost empty leaderboard for it.

You also don't need an official category here to run it and can use a Google Sheet to keep track of times.
