I played it years ago, when I think it had not yet been officially "released". I didn't know what I was going to find, and I think that partly improved the experience. Few games have frustrated me as much as DD, the stress issue on every character carried over to stress in my real life hahaha, but I enjoyed getting into those dungeons and facing every boss.
The narrator in this game is awesome, I love every sentence he says and especially how he says them.
It is one of the most stressful games for sure. Yous should give the sequel a chance, it's a different game, a little easier than the Darkest Dungeon.
