Darkest Dungeon [Official Site, Steam] is a hard and long game, but thankfully the developers know what to do about it. They are planning to add in a shorter game mode for you.
They also recently added in gamepad support, but it's limited to showing Playstation button glyphs right now. They plan to add more to it in future updates.
An average playthrough of Darkest Dungeon takes apparently 80 hours, but this new mode called "RADIANT" will cut it in half. It will be an optional mode of course, so they aren't changing the entire game. It's for those of us with a little less free time and to help prevent players getting burnt out by the current length.
They are also planning their first DLC named "Crimson Court" which comes sometime early next year.

About the game
Darkest Dungeon is a challenging gothic roguelike turn-based RPG about the psychological stresses of adventuring.
Recruit, train, and lead a team of flawed heroes through twisted forests, forgotten warrens, ruined crypts, and beyond. You'll battle not only unimaginable foes, but stress, famine, disease, and the ever-encroaching dark. Uncover strange mysteries, and pit the heroes against an array of fearsome monsters with an innovative strategic turn-based combat system.
It's 50% off on Steam right now and it's a pretty good game, so go grab it if you haven't already.
