Floating Brick Niche is one of the most interesting levels how the world record route progressed for each category. We will probably find new routes but both MECHDRAGON and I are on hiatus.
This is absolutely one of my favorite levels to speedrun in the game, and it is quite enjoyable.
Floating Brick Niche Without Powerup
Route 1: Mechdragon developed a route that if you take the red koopa shell near the start it's much faster than using the buzzy beetle shell. I, then did it faster but I carried a springboard with me for no reason.
Route 2: Mechdragon then decided that if he carried the springboard and threw it down, he could bounce on it to save time. I, then did it faster.
Floating Brick Niche Star Without Powerup
Route 1: Mechdragon developed the ordering to throw the shells, then I did it faster.
Floating Brick Niche With Powerup
Route 1: I just flew with the blue boot to the first door to outside the first section
Route 2: Mechdragon noticed that I didn't take the red shell like the without powerup route so he decided to do that without the blue shoe.
Route 3: I flew with the blue boot below the noteblocks and did a clip into the door I was supposed to enter
Route 4: Mechdragon decided to fly under the stage with the leaf and enter the 2nd door that way. I then did it faster.
Floating Brick Niche Star With Powerup
Route 1: Mechdragon developed a method with a leaf to get the red koopa shell and preceded to do this order: 1, 2, 3, enclosure.
Route 2: I made 3 improvements to the route. I noticed that it was easier to avoid all the noteblocks without a leaf and with using a spring. I also found out that 2, 3, 1, enclosure was faster so I developed ideal ways to throw shells in that order. I also noticed that Mechdragon took up generator space so I bounced on one of the buzzy beetle shells instead.
