Haha, thank you for your feedback. I agree that it's too hard after getting the feedback.
The vines are a chain of 5 pixel long, RigidBody2D's in static mode, chained together similar to some of rope tutorials you can find by googling "Godot rope physics". While in static mode, their size and position is controlled manually, and I rotate the segment the player is holding towards the plater at a rate proportional to the vine's width, but clamped.
When the vine dies, I just change the collision layer and set the vine segments back into RIGID body mode.
The main logic is here. https://github.com/JPTeasdale/VineClimber/blob/main/components/vine/VineSegment....
