This looks cool, though...kickstarter :/
Looks like they got more than enough money to finish it at least
Kickstarter doesn't pay out unless goal is reached (it's in their policies).
Okay, so I picked up the early access.
They state possible instability and glitches. Here's the glitches I've run into:
Some missions/quests are not able to be completed, some of the time (due to saving the game and the mission state not being preserved properly). This is a known bug and they're working on it.
Now into the details of what it feels like:
Single player The Ship, with crafting in a procedural world, and a focus on drugs for the story and no multiplayer (nor MP planned as far as I know, at least not initially).
There's no specific story (yet) save for the prologue (which gives you a limited background on the character you're playing, which is one of 3 planned), you can find out more about the history of the town and whatnot through completing missions (not all missions work and not all stories are fully implemented).
Here's the Steam Page

Difficulty: Honestly, the same as any other survivalist crafting based game that also uses procedural generation, sometimes you'll have it easy, sometimes the difficulty ramps up immediately.
Is it fun?
As of right now, there's a little bit left to be desired (it is early access after all), but I'm having fun with it overall.
