Sekiro failure gang, checking in! I made it super far in that game, and then one boss in particular (Owl) just totally exhausted me. After many attempts with what felt like little to no improvement, I decided I was done with the game. There's too many great games and so little time in my life these days. I can't be bothered to pound my head against the wall for too long before I decide it's time to move on. I did something similar with Cuphead too. I don't think there's any shame in it.
Life is short and time is precious. Play what you love, and love what you play. That's what I say.
