haha, there is not much to it (also I'm pretty sure your channel has more daily views than this page already)
noclip is a bit tricky, it's hidden behind debug mode:
to enable debug mode have a file called:
icon1.ico
in the same folder with the LAB.exe (contents don't matter, only the filename)
and then during play hold down V
while moving to go through walls
(you can also hold G and H for debug rendering in this mode)
