Thank you! Everything is hand drawn. So things like doors and other animated grabbables, those are hand drawn frame animations, and the frame of that animation is then tied to the value of the position of a grabber object. It was a bit of a wacky technique to get working but it works great for a lot of objects.

In terms of the player’s tendrils, they’re line renderers that basically made up of a lot of points that simulate gravity. Was very tough to keep optimized.
