Wrench Skip is a very useful skip used to unlock hard mode early. Here's how to do it!
Before you begin, make sure you have snap turning enabled. (Default settings seem to work for me) Also ensure you have a decently sized playspace. (I don't know if or how Wrench Skip works for PS5)
To begin, teleport to the faz-wrench area. Then, walk forward as far as you can. When you can't walk forward anymore, turn around in real life and snap turn to the right 4 times. Repeat the process until you clip into the room.
Here's a demonstration from my current PB. (Note that I do fuck it up when I clip onto the stage)
Hope this helps!
Also, ignore the time at the start. That was from a failed run.
I was doing any% runs and I noticed that the skip used to skip Opilla's "fight" was patched. Either that or I'm doing it wrong. (On latest version) (Was using Alt-F4)
