At one of my run i accidentally make pretty big time save. Here video Got stuck at elevator for some reason for a few second, but is sure worth it. Then i spend about 1 hour to do this again but failed. Any idea how i did this?(yea lol, i totally dont understand how its hapened).

gonna give it a try tomorrow, never saw it in any other runs i saw or did. i assume you skipped one of the triggers that make you walk like a snail, and the triggers in this game don't actually care if any other "core" characters are at the same place, as long as the player is. you can witness this pattern in literally any other level of the game, most notably escape section w/ oob jump
