§ 102 . Subject matter of copyright: In general
(b) In no case does copyright protection for an original work of authorship extend to any idea, procedure, process, system, method of operation, concept, principle, or discovery, regardless of the form in which it is described, explained, illustrated, or embodied in such work.
You can copyright a poem: "The rat ate a cat, and the bone chewed on the dog." But, you can't copyright the idea or concept of being playfully backwards. Thus someone else could create a poem without infringing on your copyright, though obviously using your idea: "The water went up the falls, and the ocean is above the sky."
Impassables are easily classified as an idea, concept, and/or principle. They can not be copyrighted in general. Only the visual portion of the image regarding the impassables can be copyrighted; similiar to the exact words of the poem examples. However, it is extremely bad form to make an exact copy of an idea, and it would look bad to players from that site to see an exact copy here.
