Religion

The following is based on an interview with developer Armin Ibrisagic about the symbolism of religion in Goat Simulator, with a bit of additional speculation from .

GoatVille is intended to be Purgatory, with the goats being trapped in a realm of eternal stasis. The goats are likely former humans, with the form of a goat chosen for being a common sacrificial animal. Though other humans exist in this realm, any attempt to interact with them causes them to immediately go inert or just run away. You can never be part of the group, but are always alone.

Through their actions, goats can attempt become closer to Heaven (Him Len) or Hell (Helvete), indicated by the signs on the two tunnels at either end of GoatVille.

Hell is obviously associated with the Pentagram, where humans or other goats can be sacrificed to obtain the power of Devil Goat. It is also associated with Goathenge, which represents "the backwards and old ways of humankind that need to be destroyed for progress to be made". Interestingly, Coffee Stain Studios, the creator of Goat Simulator, is also physically close to Hell.

Heaven is associated with the B[e]acon, which "represents research, progress, and hope". The trap once you go to Space shows "things cannot be rushed before you are ready". If interacting with humans represents trying to reach out to the goat's former life, than ignoring humans to obtain the power of Angel Goat may mean one must let go of their Earthly attachments to reach Heaven. Heaven may also be associated with the Crane, which is literally the object closest to the heavens, and is used in the creation of greater things. The Jet Pack is also found at the Construction Site, which allows you to get even closer to the heavens.

Goat City Bay
The article in question was written before the release of Goat City Bay, so any speculations along these lines may or may not apply to that map. The sign on the tunnel you start in front of reads "PurgTown", implying you're no longer in Purgatory. (It's also worth noting that if you stand still after loading you'll get run over by a car and get knocked into Purgatory.) The world is filled with more Earthly desires, like dance parties, amusement parks, shopping, and illegal substances. And Heaven and Hell have come down to Earth, in the form of the alien and Slender Goat respectively.

Protests
According the developers, certain locations have symbolism not pertaining to religion as well. The protesters, for example, represent the protests taking place in Ukraine. There are likely others, such as the hillbilly car in the field.
