CHEESENATER's run really opened my eyes to the potential of the corner boosts for the any% and even secret ending categories. Doing the boost off the fence isnt too bad and doing it off the ice pillar isnt too bad, however getting the super speed roll in the Ice room is super hard. I have been trying to lab it out and have only gotten in 4-5 times in like 2 hours of playing.
It seems you have to roll just at the corner between solid ground and the ice floor in order to get it but we should try to figure out a consistent setup. :^)
Ok I looked at CHEESNATER's run frame by frame and it looks like he hit the last pixel of the corner and got boosted off of that since his path turns really sharply. I don't know if there's going to be a consistent setup for it because of how precise it looks but there might be some tricks to time it right it'll just take a lot of practice
