Why no warpless speedrun like in smb?

Warpless is just very similar to All Castles except you can skip either Worlds 3 or 4 (4 is faster than 3), and you can do 5-Airship instead of 2-Secret.

But you can unlock warps inside the world (W5, W7, W8) if it is all castles.

Following the format of warpless from every other NSMB game, a "warp" would only be considered something that takes you from one world to another. World 4 (I believe) in NSMB2 is a perfect example of this.

What about no secret exit except 5-4 & 5-5?

You could do a run of it. It doesn't have to be on the boards for you to do a run of it.

Why I fucking need to open this forum if I don't want a board for this?

Because a category needs to peak enough interest to warrant a leaderboard for it. I'm not going to just add a category before anyone does a run of it and even then, just only one person running it.

Please do not create a warpless category.
