1) Wallpumping and Airpumping. I know what they are, the directions they work in, and the theory behind it. Maybe I'm doing it correctly in my runs, I don't know, but I can't see Link moving any faster. And I can't get sub 6 minutes on the Escape (starting at file select). So I -feel- like I'm doing it wrong.
Wall and Airpumping as far as I know moves you forward by one pixel every time you do it. It's like Armpumping in Super Metroid. You gain one pixel every time. It's not noticeable but it saves time from frames to seconds depending on the length of the run you are doing.
