The reason behind it probably not having much a description for the game is because it isn't completely finished to the point of having a defined backstory or abstract of its contents. If this is your first time here (I should note that I am relatively new with having an account on here), that most of the games here will have a patreon if it looks as though it has a lot of detail and work put into. Not saying the other games and tools here that don't have patreons aren't great - I'm saying that you can probably guesstimate that a patreon exists as the detail came from a group of people rather than one person
Hope that made any sense, cuz I think I just brain dumped onto here...
