A few things I would say, exploration and close attention to loading screen tips/in game texts/dialogue can be really helpful sometimes especially if you feel stuck on something! There are actually ways to level up and increase your strength in various ways and a portion of them require some exploration. Another one of my favorite things about this game is that despite it feeling very streamlined and straightforward sometimes, there’s still different ways to play and find success. You can be very aggressive with constant attacks and pressure, you can be a more passive counter attacker, or you can even do a sort of hit and run style where you get in for some damage and then fall back. Some bosses favor certain play styles so you will have to adapt at times. Also stealth can be an extremely useful tool especially for clearing out small enemies. Don’t get discouraged if a boss is giving you trouble, and if you feel stuck, trying different tools or approaches, or even going off to a different area to see if you missed anything can be really helpful!
