Just completed it at 21.5 hours. Left a few side quests undone, and apparently didn't find a few secrets. My initial thoughts upon completion are that it is a good game, but the nucleus of a great game. The devs are looking to turn it in to a franchise, and I hope it goes well as I imagine they will learn from this and create an amazing sequel. The sequel would need to be a lot bigger though. Whilst the areas are good, and quite intricately designed, the overall world feels a bit small.
The story is nonsense, and the lore underbaked, but there is potential. Voice acting is pretty poor, and the animations aren't great. In this regard it reminds me of The Witcher(well there are Witcher devs on the team)in that the first game had poor VO, animations and translation problems, but they sorted it for the next game.
Overall, I would recommend the game if you like the Souls games or the kind of challenging gameplay they offer. Be aware though, that it does have a fair few bugs, though I only experienced a few myself.
Will I play NG+?...I probably will actually.
