(Easy & Normal) Buffering While Loading Stage
0While you load as stage, if you do inputs with your control stick you will hear some noise. When you stop hearing these sounds that indicates that you can start buffer your inputs. If you do hold, for example, forward earlier than that you will lock yourself out and you will not move at all even when you have the control stick pointing forward. This seems to only be the case when first loading a stage from the stage select screen. If you retry or go to the next stage after completing one you can buffer inputs right then and there without having to worry being locked out of your buffered inputs. This is useful because in most stages you will spawn in the air and then drop down to the ground.
This is not a big deal in an IL run, but for a full-game speedrun this loses time. So if you use the concept of buffering your inputs you can already hold forward and also hold the Thruster (RT) and as soon as possible you will be moving and not waste any time.
