So i've been quite into speedrunning 1-4 and i've seen people punching the coin as if there was no punch cooldown (idk how is that called). I tried so many times but i never even came close tho that speed. Also whenever i try to ultraboost when going out of the spawn i either get too much vertical speed and just bump ito the ceiling and loose all my speed or i simply go too slow so basic slam storage is faster (i've tried doing this sooo many times and never succeeded). What am i doing wrong?

Punching has no input buffer so you need to time it, trying to quickly time your punches is always going to be faster than spamming F I'm not sure for normal ultraboosting but the God UB requires a specific lineup to make it to the checkpoint in 1 bhop, you can probably check some of the runs that use God UB and try to replicate it as close as you can since even if you mess up the lineup you should still be able to make it to the checkpoint with 1 bhop and 1 slidejump

thank you)

btw for anyone struggling with ultraboost in the beginning of 1-4 you need to jump next time you hit the ground after UB not slide jump
