I've only played this game for an hour and i already love it to bits.

I waited months for the games release and it was not a let down what so ever, and more or less better than what i expected.
The art style is amazing, it feels like a 2D dark souls but yet still 3D.
The sound design is done so well in this game, it really sets the mood and you can feel when you are in a safe relaxing area or approaching a boss fight. Some sounds in the game even fade out when you go to different areas and really add to the realism of the game.
The boss fights are so unique between each other and I love how quick you are to come by a new boss. Even the first few boss fights are really good at giving new comers information on how the mechanics of the game work.
Their are also many different builds and unique game styles, and some if you find the right build can help with the difficulty of some bosses to an extent.

Overall i would seriously recommend this game, especially to anyone who loves Dark Soul's or Boss rush games in general
