In the guide it sais that 01 escape is slightly different using unpack 4104 but it doesn’t tell me what’s different and the tutorial didn’t work

Here is a way to do it

But before the video you have to load the area but my head always gets stuck and but that doesn’t happen in the tutorial

Do you have a clip of it?

Watch 0:19 to 0:23 that is the load glitch that I was talking about

are you entering it sideways? i think you need to enter it sideways

Also I'd recommend joining the portal speedrun discord for future problems and ask in the #help channel.
