in the tutorial is there a way to get to the secret door skip with the noclip glitch active?

Do level dupe instead, saves you a bunch of time.

how do i do that

i cant see anything because i dont want to buy tokens

You don't have to, you can just cancel the menu and it works.

?

i try going to hub and then quickly pressing 'test here' and it just deletes the hub entirely

Record me a video of how you're doing it.

ok

I think you haven't even watched the video, have you?

i did watch it, i just have absolutely no clue as to whats happening

Write down exactly what the video does and try doing it yourself.

after the door is placed i cant see what happens in the menu
