(Plastic) conveyor belts

[calibayzone]

Plastic tiles are not that big of a movement gain atm, as the dupes late game are so fast that having to jump across ladders, etc can easily take more time than climbing or running on a straight path.

But conveyor belts provide a very different and engineering-heavy mechanism to reduce dupe travel time. Basically they act as mesh tiles where items will fall and go a specified direction. Items can fall off one belt and onto another, or travel 45 degrees up/down if the belt tiles are diagonally placed. Belt tiles could be just tiles from a dupe's point of view, or be in their own layer like pipes.
