I was playing the first level on a new save file. when I finished it, I clicked a bunch of times, then it took about 5-6 seconds for to load the hub world. (for my computer it normally takes 2-3 seconds) then it froze up for about 3 seconds. then gave me the credits. I clicked continue and it brought me to the main menu. then I clicked on continue again and I had every level unlocked. This was on turbowarp, with a controller. i do not have a video. i will try to get one soon.

There could be a category where skips are allowed but timing does not stop when you transition between games.

Get the Ranger and shoot a Waddle-Dee in the face as fast as possible. My PB is about 13 minutes. I already suggested this in another form and people seemed to like it.

This seems like a viable category for this game.
