Been playing on Hard whole time and it is manageable. Love the story, graphics but the combat is really really where it shines, so so good. I'm even doing tons of side quests bcus thy are fun. If Witcher 3 had this type of combat (not saying samurai stuff per se but the way its executed) I would have enjoyed it. Parry just feels so good, honestly it's my favorite game tht uses parry even like it better than Sekiros feel.
Btw I'm on Act 2, be careful there is a gkutch in the side quest about "missing children by the lake" where you'll examine stuff and you'll just freeze there, just restart the game and go back it should fix it.
Enjoyed the game in the beginning but it has infinitely gotten better. Duels aka boss fights are so well done and feel movie like, this game went from an 85 to a 90 for me
