I've been grinding Chapter 4 a while ago, since it's been fairly vanilla so far. There had to be something there to mess and toy with, and after giving it a go, it's been pretty exciting. This is part of what I got out of it.
Gonna post this here in case someone only checks the forum. More coming.
Any associations with Legend of Zelda are very unintentional, but it fits imo ;)
Quick update to keep everyone who might want to run this on an even playing field.
To clarify, clicking right analogue stick doesn't work for any fixed camera angles that occur when you hang or airwalk from some ledges, where you're camera-locked from the very beginning, so it doesn't work in Episode 6's Pick-Socket skip for example.
You can only unlock cameras in situations where you're airwalking freely, but suddenly the camera freezes and stops reacting to any of your movement inputs.
This is especially useful for the airwalk to the minefield in Episode 3 and the big airwalk to the cube in Episode 7. There might be other uses, but that's it for now.
... because you get the Junk Bolt from Headache Tommy in the Leaking Brain fight I was unable to beat the Zorn at the end of Episode 3.
Just wanted to let yall now. If you somehow could skip the last hit on the Zorn, it would be possible to airwalk from the usual first airwalk spot in Episode 3 directly to the minefield/Zorn fight.
Skip setup starts at 1:30 until 13:45, in which I go over how to airwalk to the end of the level in detail.
Especially interesting moments from 0:57 to 2:30, 16:00 to 21:00, and 26:27 until the end
