I would describe it as a sort of fantasy/mythical horror. The game/story is about an (obviously) fictional monster that tortures people in their nightmares until they are shells of their former selves. Once they become these shells. They are consumed by the monster, to be used in the future torturing of other victims. Our protagonist is one of these victims. Whether he can fight back and attempt escape is up to the player/reader. It is currently unfinished. It should be finished in maybe a month or two. If only because of personal timing issues.
I am not quite sure how long it will be, but I will attempt to run it to the length that I find suitable to maintain the attention of someone playing/reading this.
