Thinking we should have a place to write down the useful tech that may not be immediately obvious.
Film Through Walls:
Does what it says. The prompt for picking up film has some leeway and if you know where to aim you can snag it from the other side of a wall. Currently using this on Mauao 100%, but it can also be used on Otumoetai if the route changes.
Animation Cancels: Film Pickup (x2)
The film pickup animation prevents you from entering the camera. You can interrupt a pickup in progress with a lens switch, or you can skip it by picking up the film as you enter the camera.
Not sure how this might be useful, but found it while testing wall clips in the latest version (post-switch release / speedrun mode patch).
You can store jump height by sprinting against a surface and mashing jump, then breaking contact with the surface.
