i want to know if a ledge jump could skip the crazy precise jump at the start

Which ledge jump is it? Because I might be able to help.

the first platform on level three

a long time ago that used to be possible but with how physics are now, since the starting platform isn't a slope and the next platform is too far away, ledge jumping doesn't work

so we can't help you out buddy. :/

it was worth a shot
