I did not think I'd get this far
Knowing nothing about how to record videos, let me explain some code with a screenshot

What I've done with a Godot Tilemap is nothing short of witchcraft and it doesn't use Custom Data Layers because I don't want to test my luck and sanity. The game world will take all the tiles in the game world and add them to a grid dictionary, which each key has a cell data class holding my important info. Each Tile, depending on which tile it is, has a receive and transfer direction, which each object checks to see if this tile's transfer direction and the next tile's receiving direction are the same. If they are, a tweening of the object as smooth as hot butter occurs to make it look like the object is being moved across the conveyor belt.
It may not be much in comparison to the work some of y'all have put in but this is half the work for me. I could probably close out the mechanics sooner rather than later if I pace myself. The main gimmicks are rotating conveyor belts at intersections and flipping a switch that reverses all conveyor belt directions in order to drop objects into goals. Not the most interesting game in text but it's simple and it's arcadey and all the Tilemap sorcery was the bulk of the work.
