Wooden Platform

A  is a mountable bridge / platform object, that can be placed adjacent to any physical block on any side of it. They can also be placed directly on any  natural  dirt and stone back walls. They can be placed over top of concrete back walls, provided there is a natural wall block behind the concrete back wall. They can be moved through with no restrictions, besides being able to walk on top of them. Pressing will have the player drop down from atop the platform. Objects and wall blocks  cannot  be placed on top of them. They provide poor stability support when building structures, and are quite fragile when being burdened with too much weight. Easily destroyed by damage.

In-Game Description
Can be built on background surfaces. Used to walk or place machines on while still being possible to move over.
