I know you are eventually going to beat it. Don't just give up on Sekiro. I know it's damn hard but it's beatable too.I finally beat this game man! This game was so difficult! haha, only took me ... 6 months to beat this game. I wasn't going on a marathon, its mostly when I have time on the weekends.
On another note, I did try out 'sekiro' for ps4, nope! can't do it! its difficult too.... reminds me of dark souls. I can't beat that game too... hahah
