I have been following a recently released early access PC game called Darkest Dungeon, which has been a top seller on Steam. I've watched several videos of youtubers and online streamers playing it and it certainly looks like a lot of fun. Has anyone bought it? If so, what do you think?

From the official website.
Darkest Dungeon is a challenging gothic RPG about the stresses of dungeon crawling. You will lead a band of heroes on a perilous side-scrolling descent, dealing with a prodigious number of threats to their bodily health, and worse, a relentless assault on their mental fortitude! Five hundred feet below the earth you will not only fight unimaginable foes, but famine, disease, and the stress of the ever-encroaching dark. Darkest Dungeon focuses on the humanity and psychological vulnerability of the heroes and asks: What emotional toll does a life of adventure take?
